AD720JP

AD720JP RGB to NTSC/PAL Encoder | Analog Devices

The Analog Devices AD720JP is an RGB-to-NTSC/PAL video encoder integrated circuit with a 28-pin PLCC package. It produces a composite video output and separate chrominance and luminance outputs for S-Video, supports selectable NTSC or PAL encoding modes, and is designed to drive 75-ohm reverse-terminated video loads. The device also requires no external filters or delay lines, simplifying RGB video encoding systems. An RGB video encoder is a specialized interface IC that converts separate red, green, and blue component signals into a composite analog video waveform accepted by NTSC or PAL displays. Within the product hierarchy, the AD720JP belongs to the video encoder and converter class, then the broader interface IC and signal-conversion categories. It sits between an RGB graphics source and legacy composite or S-Video equipment. The AD720JP's principal features include logic-selectable NTSC and PAL operation, automatic selection of the appropriate encoding mode, separate S-Video chrominance and luminance outputs, and direct drive capability for 75-ohm reverse-terminated loads. The integrated implementation eliminates the external filter and delay-line networks normally associated with discrete RGB-to-composite encoding circuits. Its 28-pin PLCC package provides a compact surface-mount solution for industrial video, broadcast, control-panel, and embedded display equipment. Technically, the encoder organizes RGB component information into a composite color signal while providing separate Y and C outputs for S-Video equipment. Composite output and S-Video can therefore be used in the same design without duplicating the source RGB interface. Logic-selectable encoding allows one board design to support multiple regional video standards, while automatic mode selection can reduce operator configuration where an appropriate control signal is available. Typical applications include industrial monitoring panels, professional video equipment, broadcast-system interfaces, image-processing subsystems, video test equipment, and legacy display controllers that require conversion from RGB component video to NTSC or PAL. In each case, the device is most useful where compactness, integrated filtering, and direct 75-ohm loading are more important than the low latency of a software-based video pipeline. For a robust implementation, route the composite and S-Video outputs with controlled impedance and provide the termination network required by the target video standard. Keep sensitive analog routing away from switching nodes and use a stable ground reference between the encoder and the video connector. Confirm the selected encoding mode, electrical levels, and termination arrangement against the Analog Devices datasheet before releasing the production layout. This product page combines the AD720JP's confirmed encoding capabilities with application guidance, design cautions, comparison data, and documented procurement information. It helps engineers evaluate the 28-pin PLCC device for compact RGB-to-NTSC/PAL conversion while keeping package, output-routing, and video-standard decisions explicit.

AD721JP RGB to NTSC/PAL Encoder | Analog Devices
AD721JP

AD721JP RGB to NTSC/PAL Encoder | Analog Devices

Analog Devices AD721JP is an RGB-to-NTSC/PAL color-signal encoder integrated circuit operating from ±5 V supplies and housed in a 28-pin plastic leaded chip carrier package. It generates composite video together with separate chrominance and luminance outputs for S-Video, drives 75-ohm reverse-terminated loads, and requires no external filters or delay lines. Its selectable encoding modes automatically configure the device for the appropriate NTSC or PAL timing convention. An RGB-to-NTSC/PAL encoder is a video-signal conversion IC that accepts red, green, and blue analog color components and combines them into a standard composite television signal. Within the broader signal-processing hierarchy, the AD721JP belongs to the color-signal encoder class, which supports display, broadcast, video-production, image-capture, and industrial monitoring systems. Separate S-Video outputs retain chrominance and luminance as independent signals, while the composite output combines the three RGB input channels for conventional video connections. Key features include logic-selectable NTSC and PAL encoding modes, a composite video output, individual chrominance and luminance outputs, and no requirement for external filters or delay lines. Its ability to drive 75-ohm reverse-terminated loads simplifies analog video output design because downstream cable and video-circuit impedances are matched at the device interface. The 28-pin PLCC package also supports compact, socket-compatible legacy video equipment layouts. Internally, the encoder translates the red, green, and blue input signals into the amplitude and timing relationships required by composite video. Logic selection determines whether the generated chrominance information follows NTSC or PAL conventions, reducing the need for separate encoder ICs when a system must support both standards. The ±5 V analog supply arrangement provides compatible operating rails for the RGB input, modulation, and output stages commonly used in professional analog video electronics. Typical applications include professional video switchers, frame synchronizers, broadcast and production equipment, industrial video monitors, test and measurement instruments, RGB-to-video interface boards, and legacy computer-video adapters. Because the IC produces composite and S-Video simultaneously, it can feed separate baseband video sections without requiring duplicated encoding circuitry. A key design consideration is signal termination. The composite and S-Video outputs are intended for 75-ohm reverse-terminated loads, so downstream cable routing and impedance matching directly affect picture quality. Place supply bypass capacitors near the device, route RGB inputs away from output nodes, and preserve the logic levels required for NTSC/PAL mode selection. Verify the complete color-adjustment and synchronization implementation against the Analog Devices AD721/AD721 datasheet. This product summary consolidates the encoder functions, package details, output capabilities, application guidance, and replacement considerations into a design-focused reference. It also identifies where a same-footprint candidate requires review rather than presenting every related device as an automatic substitute.

AD7247ABRZ-REEL

AD7247ABRZ-REEL - Dual 12-Bit DAC | Analog Devices

The Analog Devices AD7247ABRZ-REEL is a dual 12-bit CMOS digital-to-analog converter with a 24-lead SOIC package. It provides two 12-bit DAC channels, supports operation from 12 V to 15 V supplies, and uses an on-chip 5 V reference or an external reference through the REF OUT/REF IN function. The device also includes output amplifiers and reference-buffer amplifiers, making it suitable for precision signal-generation and control applications. A DAC, or digital-to-analog converter, is an integrated circuit that converts a digital code into a proportional analog voltage or current. The AD7247A is part of the DACPORT family and uses a dual R-2R architecture with precision CMOS circuitry. In a system hierarchy, a DAC sits between digital control logic and analog output circuitry, while the AD7247ABRZ-REEL provides a compact dual-channel conversion function for instrumentation, industrial control, and test equipment. Key features include two independent 12-bit DAC channels, a 125 kS/s sampling rate, an 8 microsecond settling time, and support for single- and dual-supply operation. According to the manufacturer product information, single-supply output ranges include 0 V to 5 V and 0 V to 10 V; dual supplies add an additional plus or minus 5 V range. The SOIC-24 package supports surface-mount assembly and is supplied in tape-and-reel packaging for automated manufacturing. The AD7247A family is fabricated using Analog Devices Linear Compatible CMOS, or LC2MOS, technology. LC2MOS combines precision bipolar circuit techniques with low-power CMOS logic, helping support accurate digital-to-analog conversion in a single integrated device. The AD7247ABRZ-REEL is identified in distributor listings as a 24-pin, 12-bit, dual DAC and is categorized as a SOIC industrial-grade component with an operating temperature range of -40 °C to +85 °C. Typical uses include programmable voltage sources, industrial process-control outputs, laboratory instrumentation, data-acquisition systems, and precision analog signal generation. Because the converter has two channels, it can drive paired analog outputs from a shared digital control system. The external-reference option allows designers to improve stability or scale the output range when the application requires independent reference control. Designers should verify the supply rails, reference configuration, output range, settling requirements, and digital-interface timing against the AD7247A datasheet. Decoupling capacitors should be placed close to the supply pins, and the analog output routing should be kept separate from fast digital switching paths. The manufacturer documentation also confirms that the family is available in 24-pin plastic and hermetic DIP packages and 24-lead SOIC packages. This page combines verified manufacturer and distributor information with package-specific comparison, selection guidance, and practical design notes. It is intended to help engineers identify whether the AD7247ABRZ-REEL matches the required resolution, channel count, supply arrangement, package, and precision application.

AD724JR RGB to NTSC/PAL Video Encoder | Analog Devices
AD724JR

AD724JR RGB to NTSC/PAL Video Encoder | Analog Devices

Analog Devices AD724JR is a low-cost RGB to NTSC/PAL video encoder IC that converts red, green, and blue color-component signals into luminance and chrominance signals for composite video generation. The device operates in a 16-lead SOIC package. According to the manufacturer product page, the AD724 provides luminance, chrominance, and composite outputs, with all three outputs able to simultaneously drive a 75 ohm load. Its primary function is to translate separate RGB video information into the analog baseband signals used by NTSC or PAL video systems. A video encoder is an interface and signal-conversion integrated circuit that bridges an RGB graphics or video source with a composite-video output stage. The AD724 is therefore positioned within the video interface hierarchy rather than as a general-purpose processor or memory device. In an analog video system, RGB signals carry separate color information, while composite video combines luminance and chrominance into a single signal. This makes the encoder useful in legacy video generation, test equipment, video processing, and educational electronics. The AD724JR supports both NTSC and PAL standards, giving the design flexibility to address different regional video formats. Its three principal outputs allow a system to use luminance and chrominance separately when additional processing is required, or use the composite output when a single video connection is needed. The 16-lead SOIC package is surface mountable and supports compact, automated assembly. The exact electrical limits, timing values, supply requirements, and detailed operating ranges are defined in the AD724 manufacturer datasheet. The encoder’s signal architecture makes it important to treat analog video routing as a controlled-impedance and grounding problem. RGB inputs determine color and timing relationships, while luminance and chrominance outputs are intended for downstream amplification, termination, or video-processing stages. Using the correct termination and impedance environment helps preserve signal amplitude and reduce reflections. The manufacturer datasheet specifically recommends connecting analog and digital ground pins to the ground plane through short, low-inductance paths and bypassing each power supply pin with a 0.1 uF capacitor and approximately 10 uF tantalum capacitor. Typical applications include composite-video signal generation, NTSC and PAL video test fixtures, RGB-to-composite conversion modules, industrial imaging interfaces, video timing demonstrations, and instrumentation that must produce a conventional analog video output. Because the AD724JR is a dedicated encoder, it is most appropriate when the design already contains RGB signals and requires a standardized luminance, chrominance, or composite output. The principal design consideration is ensuring that the input levels, synchronization requirements, and output termination match the intended video standard. PCB layout should preserve short analog paths, provide stable decoupling, and separate sensitive video routing from noisy switching or high-current paths. Review the manufacturer datasheet pin-description table before assigning tracks, especially when the same board must support both NTSC and PAL configurations. This product page combines the manufacturer description, package information, search-specific documentation intent, practical bypass and grounding guidance, and a conservative replacement assessment. It distinguishes what the AD724JR is designed to do from broader video-system requirements, helping engineers determine fit before modifying an existing PCB or requesting a quote.

AD725AR - RGB to NTSC/PAL Video Encoder IC | Analog Devices
AD725AR

AD725AR - RGB to NTSC/PAL Video Encoder IC | Analog Devices

The Analog Devices AD725AR is a low-cost RGB to NTSC/PAL video encoder integrated circuit that converts red, green and blue color component inputs into a composite video signal, while also providing separate chrominance and luminance (S-Video) outputs, all in a 16-lead SOIC package. An RGB-to-NTSC/PAL encoder sits at the boundary between graphics and video: it takes the parallel digital-equivalent RGB voltages produced by a graphics controller, CRT/LCD video card, character generator or test pattern source and converts them into the modulated composite video waveform that analog monitors, VCRs, and broadcast equipment expect. In the component hierarchy it belongs to the video interface IC family, which itself is a subset of interface ICs, mixed-signal semiconductors and, at the broadest level, integrated circuits. Key features of the AD725AR include composite video output for both NTSC and PAL standards, simultaneous chrominance and luminance (S-Video) outputs, a dedicated luma trap (YTRAP) port that reduces cross-color artifacts, TTL-compatible logic levels that also satisfy 3 V CMOS system requirements, an integrated delay line and auto-tuned filters, the ability to drive 75-ohm reverse-terminated loads, and low power consumption. Power-down operation allows the device to be held below 1 microamp of supply current for portable or power-sensitive equipment. Technically, the AD725AR accepts RGB inputs at TTL levels, internally encodes the color difference information onto a color subcarrier, filters it to the correct bandwidth for NTSC or PAL, and combines it with the luminance path and synchronization information to produce a composite output. The on-chip delay line and auto-tuned filters remove the need for external crystal-controlled oscillator components and hand-matched traps, which is what makes the part low cost while still suitable for consumer and industrial video gear. Typical uses include video card and CRT monitor interface logic, industrial and instrumentation video panels, video test equipment and pattern generators, security and surveillance camera analog output chains, and legacy computer and arcade display hardware being maintained or adapted. When designing around the AD725AR, remember that the luma trap port must be handled correctly to avoid cross-color, and that output drive is specified for 75-ohm reverse-terminated loads, so downstream cable and impedance matching determine the usable signal amplitude. This page consolidates the AD725AR feature set, package and ordering variants, drop-in replacements and practical design notes into one reference so you can qualify the encoder without digging through several documents.

AD725ARZ - RGB to NTSC/PAL Video Encoder SOIC-16 | Analog Devices
AD725ARZ

AD725ARZ - RGB to NTSC/PAL Video Encoder SOIC-16 | Analog Devices

The Analog Devices AD725ARZ is a low-cost, general-purpose RGB-to-NTSC/PAL video encoder housed in a 16-pin SOIC (SO-16) package, converting red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) outputs in accordance with either NTSC or PAL broadcast standards. The part is supplied in the ARZ (SOIC, tape-and-reel) grade and is the industry-standard monolithic solution for converting digital RGB or analog RGB video from graphics controllers and framebuffers into composite or Y/C (S-Video) outputs. What is an RGB to NTSC/PAL encoder? An NTSC/PAL encoder is a mixed-signal IC that accepts red, green and blue (RGB) video data — either as analog voltages or digital codes — and synthesizes a composite analog video waveform conforming to the NTSC (M/NTSC, 525-line, 60 Hz) or PAL (625-line, 50 Hz) broadcast standard. The encoder sits in the analog signal chain between the source (graphics controller, video DAC, framebuffer) and the display or modulator (TV, modulator, capture card). In the broader IC hierarchy, the AD725 belongs to the video encoder / video DAC family, itself a sub-category of display drivers and serializer ICs. Key features include integrated luma (Y) and chroma (C) outputs, on-chip subcarrier generation, an integrated luma trap port for clean composite video, and a TTL-compatible digital interface for input format selection. The AD725 supports both NTSC-M and PAL-B/D/G/H/I/M/N standards with simple mode strapping, eliminating external modulator hardware. Operating from a single +5 V analog supply with low power dissipation, it requires only a handful of bypass components and a 28.63636 MHz (NTSC) or 26.84325 MHz (PAL) crystal. Architecturally, the AD725 uses a current-output DAC topology with internal bandgap references and switched-capacitor filtering, allowing direct connection to 75 ohm video loads with minimal external components. The luma trap output and chroma output are derived from the same RGB input through an internal color-space conversion matrix and subcarrier modulator. Typical applications include set-top box composite video outputs, video game consoles, surveillance DVRs with analog outputs, legacy industrial video overlay boards, and RGB-to-TV converter dongles. The AD725 is also common in FPGA evaluation platforms requiring analog video output and in low-cost broadcast or test equipment that needs composite NTSC/PAL modulation. Designers should note that the part requires a high-frequency crystal oscillator reference and proper 75 ohm termination at both composite and chroma outputs. Bypass the +5 V supply with a 0.1 uF ceramic capacitor plus a 10 uF tantalum or electrolytic capacitor placed within 5 mm of the supply pin to meet PSRR specifications.

AD725ARZ-R7 - RGB to NTSC/PAL Video Encoder | Analog Devices

The Analog Devices AD725ARZ-R7 is a very low cost general purpose RGB to NTSC/PAL video encoder IC housed in a 16-pin SOIC (0.295 in / 7.50 mm width) surface-mount package, supplied in tape-and-reel packaging (the -R7 suffix). It converts red, green, and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. A video encoder is an interface IC that sits at the boundary between a digital or analog graphics source and a standard-definition composite video display. In the signal-chain hierarchy, it belongs to the video encoder -> video interface -> mixed-signal IC category, translating RGB component video into the composite waveforms that analog TVs, monitors, and recording equipment expect. Key features include simultaneous composite video output and separate chrominance and luminance (S-Video) outputs, a luma trap port that eliminates cross-color artifacts, TTL-compatible logic levels for direct interfacing with standard digital circuitry, and an integrated chroma delay line. These functions normally require several external components in discrete implementations; the AD725 integrates them on chip, which is the basis of its very low system cost. Technically, the AD725 performs analog matrixing of the RGB inputs into the Y (luminance) and quadrature-modulated C (chrominance) components, with a subcarrier locked to an external color burst crystal reference. The luma trap port allows the designer to notch the chroma subcarrier from the luma path, preventing cross-color artifacts on high-saturation images. NTSC or PAL operation is selected by pin strapping, and the integrated delay ensures the luma and chroma signals re-align at the output, preserving horizontal picture resolution. Typical applications include embedded graphics systems that must drive legacy composite monitors, industrial HMI and test-equipment video outputs, set-top and retro-computing video interfaces, and automotive or kiosk displays that accept only NTSC/PAL composite or S-Video input. A key design consideration is crystal accuracy: the NTSC (3.579545 MHz) or PAL (4.433619 MHz) subcarrier crystal must be within specification to keep color hue and saturation stable, and analog ground and power routing should keep RGB input noise below the encoder's signal swing to preserve picture quality.

The Analog Devices AD725ARZ-RL is a low-cost RGB to NTSC/PAL video encoder IC that converts red, green, and blue color component signals into their corresponding luminance and chrominance signals in accordance with either NTSC or PAL standards, housed in a 16-pin SOIC (7.50 mm width) surface-mount package delivered in tape-and-reel packaging. A video encoder is a mixed-signal device in the data conversion and video interface hierarchy that transforms parallel or analog component video (RGB or YUV) into a single composite baseband video signal, or into separate luminance (Y) and chrominance (C) signals for S-Video. Encoders sit between a graphics processor or video source and a TV monitor, VCR, or video capture input, performing the color-space conversion, subcarrier modulation, and sync generation required by broadcast television standards. Key features of the AD725 include both NTSC and PAL composite video outputs and separate chrominance and luminance (S-Video) outputs from the same device, a luminance trap (YTRAP) port that reduces cross-color artifacts generated by subcarrier-frequency components present in the luminance signal, fully TTL-compatible logic levels that support 3 V CMOS logic requirements, and an integrated luminance delay line. This combination allows a single, very low cost device to serve as the complete analog video output stage for embedded systems. Technically, the AD725 performs RGB-to-YUV matrix conversion, quadrature modulation of the color difference signals onto a subcarrier, and sync insertion, producing standard-amplitude baseband video. For portable or other power-sensitive applications, the device can be powered down to less than 1 uA of current consumption, which is exceptionally low for a video-grade mixed-signal encoder. Typical applications include embedded graphics boards, set-top box video outputs, industrial display interfaces, legacy TV-out ports on microprocessor systems, and video test equipment where NTSC or PAL composite output is required from an RGB source. A key design consideration is proper use of the YTRAP pin: connecting the correct external LC trap circuit suppresses subcarrier leakage into the luminance path and materially reduces cross-color shimmer on fine luma detail. Supply decoupling and standard-accuracy crystal reference for the color subcarrier are also important for color accuracy.

AD7264BSTZ-5-RL7

AD7264BSTZ-5-RL7 - 14-Bit Dual 500kSPS SAR ADC | Analog Devices

The Analog Devices AD7264BSTZ-5-RL7 is a dual, 14-bit, simultaneous-sampling successive-approximation-register (SAR) analog-to-digital converter (ADC) with on-chip programmable gain amplifiers and four comparators, operating from a single 5 V analog supply. It features dual true-differential analog input channels, throughput of 500 kSPS per channel (the AD7264-5 variant), and is housed in a 48-pin LQFP (ST-7x7 mm) package supplied on a 7-inch reel. What is a SAR ADC? A successive-approximation-register ADC is a type of analog-to-digital converter that uses a binary-search algorithm against an internal precision DAC to digitize an input voltage in N clock cycles for N-bit resolution. SAR ADCs combine excellent DC accuracy, low latency, and zero pipeline delay, making them ideal for multiplexed data acquisition, motor control, and instrumentation. Within the broader taxonomy, SAR ADCs sit alongside delta-sigma ADCs and pipeline ADCs as the three dominant precision ADC architectures, with SAR typically used at 1 MSPS-or-less sample rates where absolute accuracy and deterministic latency matter most. Key features of the AD7264BSTZ-5-RL7 include a 2.5 V on-chip reference (which can be disabled to use an external reference), an integrated programmable gain amplifier (PGA) with selectable gains of 1, 2, 4, 8, 16, 32, 64, and 128, four on-chip comparators that can be used for system-level threshold detection, and a high-speed serial interface compatible with SPI/QSPI/MICROWIRE/DSP. The dual simultaneous-sampling architecture captures two input signals at exactly the same instant, eliminating skew errors that plague time-multiplexed ADCs in phase-sensitive applications such as power conversion, vector motor control, and three-phase current sensing. Architecturally, the part pairs two independent SAR cores with matched PGAs and a shared digital control block, allowing synchronized conversion-start across both channels. The on-chip reference buffer and comparator block reduce external component count, enabling compact PCB designs in space-constrained industrial modules. Typical applications include industrial process control, three-phase motor control current sensing, vibration analysis, multi-axis inertial measurement, simultaneous acquisition in power-line monitoring, and instrumentation front ends. The 5 V single-supply operation and integrated PGAs make it especially well-suited for direct connection to low-level sensor outputs such as bridge sensors, thermocouples, and shunt resistors. When designing with the AD7264BSTZ-5-RL7, observe the supply decoupling guidance in the datasheet: place 10 microfarad and 0.1 microfarad ceramic capacitors close to AVDD and DVDD pins to achieve the rated SNR. The serial clock (SCLK) must remain stable during conversion, and PGA gain changes should be performed only between conversions to avoid corruption of the active sample. This page synthesizes distributor pricing, drop-in alternative listings, and practical design notes that go beyond what the manufacturer datasheet alone provides, optimized for engineers verifying a 14-bit dual SAR ADC choice for industrial and instrumentation designs.

AD7265BCPZ-REEL - Dual 1MSPS 12-Bit SAR ADC | Analog Devices

The Analog Devices AD7265BCPZ-REEL is a dual, 12-bit, high-speed, low-power successive-approximation analog-to-digital converter (SAR ADC) delivering throughput rates of up to 1 MSPS from a single 2.7 V to 5.25 V supply. Each of the two integrated ADCs is preceded by a 3-channel multiplexer and a low-noise, wide-bandwidth track-and-hold amplifier capable of handling input frequencies above 30 MHz, and the converter is housed in a 32-lead LFCSP-VQ (5x5 mm) package. A SAR ADC (Successive Approximation Register ADC) is a precision converter architecture that uses an internal binary-search algorithm and a precision DAC to digitize an analog input one bit at a time per conversion clock. Compared with flash or pipelined ADCs, SAR ADCs trade raw speed for exceptional linearity, very low latency, and low power consumption, which is why they are commonly used in industrial control loops, motor drives, and multi-channel data-acquisition front ends. Key features include on-chip 2.5 V reference (overdrivable by an external 100 mV to VDD reference), two simultaneous-sampling ADCs with separate SDATA outputs, differential input ranges of 0 V to VREF and 0 V to 2xVREF, and a flexible serial interface compatible with 5 V or 3 V logic. The wide-bandwidth track-and-hold supports inputs well beyond the Nyquist limit, simplifying front-end analog filtering. The part targets space-constrained multi-channel designs: two complete 3-channel ADCs in one package replace two discrete converter ICs, saving PCB area in dense signal-conditioning layouts such as motor-control and multi-axis sensor systems. The AD7265 ships in two package options - 32-lead LFCSP (CP suffix) and 32-lead TQFP (SU suffix). Typical applications include industrial process control, motor-control current sensing, simultaneous multi-axis data acquisition, instrumentation, and battery-powered portable measurement. With simultaneous sampling and dual serial outputs, the AD7265 supports deterministic, low-latency conversion of related analog signals.

AD7266BCPZ-REEL - Dual 2 MSPS 12-Bit 3-Ch SAR ADC | ADI

The Analog Devices AD7266BCPZ-REEL is a dual, 12-bit, high-speed, low-power successive approximation register (SAR) analog-to-digital converter that operates from a single 2.7 V to 5.25 V power supply and delivers throughput rates up to 2 MSPS per ADC. Housed in a 32-lead LFCSP-VQ (5 mm x 5 mm) package, the device contains two ADCs, each preceded by a 3-channel differential multiplexer, supporting 6 or 12 fully differential analog input channels in total. A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary search through successive bit trials to approximate the input voltage, delivering deterministic latency with no pipeline delay. SAR ADCs sit in the broader hierarchy of ADC -> data converter -> mixed-signal IC -> semiconductor, and are widely used when applications demand precise sampling of fast, transient, or multiplexed signals without the latency penalty of pipelined or delta-sigma architectures. Key features of the AD7266BCPZ-REEL include a dual simultaneous-sampling architecture with two track-and-hold amplifiers, an SPI-compatible serial interface with two separate data output pins, integrated input ESD protection diodes, and a wide common-mode input range. The on-chip 3-channel differential multiplexer on each ADC allows flexible channel expansion. Low power dissipation makes the part attractive for portable instrumentation and multi-channel data acquisition modules. Technical depth: The SAR core, combined with two dedicated track-and-hold amplifiers, allows true simultaneous sampling of two channels at 2 MSPS, eliminating the inter-channel timing skew that plagues sequential sampling architectures. The differential input structure inherently rejects common-mode noise, while the wide input common-mode range simplifies interface to sensors, current shunts, and bridge circuits without precision-level shifting. Typical applications include motor control feedback loops, multi-axis servo position sensing, simultaneous multi-channel data acquisition systems, instrumentation and process control front-ends, and precision battery monitoring. Differential input capability also suits the part to industrial 4-20 mA loop digitizers and biomedical signal acquisition. When designing with this part, ensure the analog input signals remain within the allowed input common-mode range to avoid code distortion, and decouple AVDD and DVDD with 100 nF ceramic capacitors placed as close to the supply pins as possible to preserve the rated SNR.

The Analog Devices AD7274BRM is a 12-bit, high-speed, low-power successive-approximation analog-to-digital converter (SAR ADC) that operates from a single 2.35V to 3.6V supply and delivers throughput rates up to 3 MSPS. Housed in an 8-pin MSOP package, the BRM suffix denotes the tape-and-reel MSOP-8 form, while the BUJZ suffix uses a TSOT-6 footprint for size-constrained designs. A successive-approximation ADC (SAR ADC) is a type of analog-to-digital converter that converts an analog input signal to a digital output using a binary search algorithm through an internal capacitive DAC, comparator, and successive-approximation register. SAR ADCs sit in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. They are favored over flash ADCs in moderate-speed, low-power, and high-precision applications because they balance speed, resolution, and power dissipation more efficiently. Key features of the AD7274BRM include a low-noise, wide-bandwidth track-and-hold amplifier that handles input frequencies well beyond the Nyquist limit, a serial SPI-/QSPI-/MICROWIRE-/DSP-compatible digital interface for easy microcontroller and DSP hookup, and a hardware power-down pin that reduces quiescent current to microamp levels between conversions. The device typically draws only a few milliamps during continuous 3 MSPS operation, making it well-suited for battery-powered and portable instrumentation. Architecturally, the AD7274BRM uses a charge-redistribution capacitive DAC core, which avoids the laser-trimmed resistor ladders required by some older SAR designs and improves linearity without calibration. The track-and-hold bandwidth exceeds the converter's Nyquist requirement, which means the AC performance remains accurate when digitizing wide-bandwidth signals such as those encountered in communications, imaging, and process control loops. Typical applications include portable battery-powered data acquisition, industrial process and motor control, communications signal monitoring, optical-sensor front ends, and general-purpose precision instrumentation where a small-footprint, low-power, moderate-speed ADC is required. When designing with the AD7274BRM, place the decoupling capacitor as close as possible to the AVDD pin and keep the analog input traces short and guarded, because the SAR front end is sensitive to high-frequency noise injected through the supply or reference pin. Use a low-impedance reference such as the ADR01 or ADR02 for best DC linearity.

AD7277AUJZ-RL7

AD7277AUJZ-RL7 - 10-Bit 3MSPS SAR ADC | Analog Devices

The Analog Devices AD7277AUJZ-RL7 is a 10-bit, high-speed, low-power successive-approximation register (SAR) analog-to-digital converter (ADC) operating from a single 2.35 V to 3.6 V supply and delivering throughput rates up to 3 MSPS, housed in a 6-pin TSOT-23 package. Key headline specifications are 10-bit resolution, 3 MSPS sampling rate, and TSOT-23-6 (UJ-6) SMD footprint. According to the Analog Devices AD7276/AD7277/AD7278 datasheet, this part is part of a pin-compatible family covering 8-/10-/12-bit resolutions with a low-noise, wide-bandwidth track-and-hold amplifier that handles input frequencies above 55 MHz. What is a SAR ADC? A successive-approximation register ADC is a Nyquist-rate converter that performs a binary search through an internal capacitive DAC one bit per clock, yielding deterministic latency, low power consumption, and no pipeline delay. SAR ADCs sit below pipeline ADCs in throughput but above sigma-delta ADCs in DC accuracy trade-offs, and they are widely used in industrial process control, motor control loops, and portable instrumentation where both bandwidth and battery life matter. The AD7277AUJZ-RL7 belongs to the broader power-management-adjacent mixed-signal IC hierarchy (ADC -> data converter -> signal chain IC -> semiconductor). Key features include 70 dB SNR at 1 MHz input, a 55 MHz input bandwidth track-and-hold, low power consumption (specified at 3 MSPS with 3 V supplies), and an SPI/QSPI/MICROWIRE/DSP-compatible serial interface. The 6-lead TSOT-23 footprint is industry-standard for high-density portable designs, freeing board space while still allowing aggressive input filtering. The part is specified for AVYING a -40C to +125C operating range, making it suitable for industrial and harsh-environment deployments. Architecturally, the AD7277AUJZ-RL7 integrates the input track-and-hold, successive-approximation register, internal reference, and serial output logic in a single die. The wide input bandwidth T/H minimizes aperture-time errors for high-frequency or transient signals, while the SAR core's inherently low noise floor supports 70 dB SNR even at full Nyquist input frequency. Typical applications include automotive sensor signal acquisition, industrial process control loops, portable medical instrumentation, battery monitoring systems, and high-speed data logging. Its combination of 3 MSPS throughput with sub-10 mW power consumption makes it well-suited for low-duty-cycle or interrupt-driven sampling architectures. When designing with this part, ensure decoupling capacitors are placed close to the AVDD pin, and use a low-impedance ground plane to avoid digital feedback into the analog input. A small RC anti-aliasing filter on the analog input is recommended for input frequencies near Nyquist.

AD7292BCPZ-RL - 10-Bit SAR ADC + 4 DACs + Temp Sensor | Analog Devices
AD7292BCPZ-RL

AD7292BCPZ-RL - 10-Bit SAR ADC + 4 DACs + Temp Sensor | Analog Devices

Analog Devices AD7292BCPZ-RL is a 10-bit, 8-channel successive-approximation-register (SAR) analog-to-digital converter with four 10-bit DACs, an internal ±1°C accurate temperature sensor, and 12 GPIOs, integrated in a single 36-pin LFCSP-WQ (6x6 mm) surface-mount package. It operates from a 1.8V to 5.25V analog supply (with a separate digital supply range on the same level), draws a single-ended analog input chain with up to 625 kS/s throughput, and uses an SPI-compatible serial interface for configuration and data readback. The part combines what would normally be four separate ICs (ADC, quad-DAC, temp sensor, GPIO expander) into one die, dramatically reducing board area in space-constrained systems. An SAR (successive-approximation-register) ADC is a type of analog-to-digital converter that performs one bit of conversion per clock cycle using a binary-search algorithm against an internal DAC; SAR ADCs are valued for low-latency single-shot conversions, deterministic behavior, and excellent DC accuracy. ADCs sit inside the broader converter hierarchy of data-conversion ICs, alongside DACs (digital-to-analog) and CODECs. The AD7292 therefore belongs to the data-conversion functional domain of mixed-signal and signal-chain integrated circuits (ICs), which are essential building blocks in monitoring and control systems. Key features include 0.6 LSB INL (integral nonlinearity), 61.5 dB SNR (signal-to-noise ratio), single-ended analog inputs with a programmable channel sequencer, integrated ±1°C local temperature sensor usable for system thermal monitoring, four 10-bit DAC outputs for set-point control, 12 general-purpose digital I/O pins configurable for ADC channels or alert functions, and two GPIO/ALERT pins (GPIO0/ALERT0, GPIO1/ALERT1) that act as out-of-range indicators when conversion results exceed user-programmable threshold registers. The part supports a wide supply range (1.8V to 5.25V) so it can interface with both 3.3V MCUs and 5V legacy systems. Architecturally, the AD7292 uses an analog input multiplexer feeding a sample-and-hold amplifier, then a SAR core clocked by an internal oscillator, with result registers read back via SPI. The four DAC channels share a common reference path with the ADC, simplifying calibration. The internal temperature sensor is junction-style, allowing the IC to read its own die temperature (a useful proxy for system thermal health in dense PCB assemblies). Two hardware alert comparators let the device assert GPIO pins autonomously when ADC readings cross configured limits without MCU intervention, ideal for safety and fault-response loops. Typical applications include power-supply voltage and load monitoring on multi-rail systems, fan/battery/charger telemetry with closed-loop control via the on-chip DACs, industrial process-control loops requiring both ADC inputs and DAC outputs, telecom and networking equipment shelf monitoring, and automotive body/comfort modules where general-purpose monitoring plus a single-chip footprint reduce BOM count. With its 4-wire SPI interface and small 6x6 LFCSP-WQ package it is especially suited where PCB real estate is tight and a microcontroller needs both acquisition and analog control on the same bus. When designing with this part, observe PCB layout guidelines: place the decoupling capacitors immediately adjacent to AVDD/DVDD pins, keep the analog input traces short and guarded, and add a low-impedance ground pour under the exposed pad of the LFCSP for thermal dissipation and reference stability. Designers should also note the SPI mode and clocking requirements, since the AD7292 uses a specific protocol with a busy/IRQ indicator for conversion completion.

AD7324BRUZ-REEL

AD7324BRUZ-REEL - 12-Bit+Sign 4-CH Bipolar SAR ADC | TSSOP-16

The Analog Devices AD7324BRUZ-REEL is a 4-channel, 12-bit plus sign, successive-approximation analog-to-digital converter (SAR ADC) fabricated on the proprietary iCMOS (industrial CMOS) process, which combines high-voltage silicon with submicron CMOS and complementary bipolar technologies. Housed in a 16-pin TSSOP package (RU-16), the device accepts software-selectable true-bipolar analog inputs and achieves throughput rates up to 1 MSPS through its high-speed serial interface, making it well suited for industrial process control, instrumentation, and motor-control feedback paths where large common-mode swings and high channel density must be acquired simultaneously. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous analog voltages and converts them into discrete binary codes for processing by digital logic. Successive-approximation ADCs use an internal DAC and a comparator to binary-search the input one bit at a time, achieving a balance between speed (MSPS), resolution (bits), and die area. The "12-bit plus sign" architecture adopted by the AD7324BRUZ-REEL adds a sign bit to the 12-bit magnitude, effectively presenting 13-bit bipolar data with an external reference, and slots this converter family between unipolar SAR ADCs and high-resolution delta-sigma converters in the broader data-converter hierarchy. Key features of the AD7324BRUZ-REEL include software-configurable input ranges covering ±10 V, ±5 V, 0 V to 10 V, and 0 V to 5 V on each channel, an external reference input (REFIN) that allows true-bipolar ±12 V acquisition when paired with ±12 V supplies, a channel sequencer that lets the firmware auto-cycle through the four analog inputs, and a serial SPI-/QSPI-/MICROWIRE-/DSP-compatible interface. The iCMOS construction delivers ±16.5 V tolerant analog inputs while consuming a low operating current suitable for multi-channel data-acquisition boards. Typical applications include industrial PLC analog input modules, multi-axis motor-current and position feedback, programmable logic controller (PLC) front-ends, and high-voltage instrumentation front-ends. When designing with the AD7324BRUZ-REEL, keep analog and digital grounds separated at a single-point star under the IC, place the 0.1 µF VDD/VSS bypass capacitors within 3 mm of the supply pins, and drive the analog inputs from a low-impedance op-amp buffer to preserve harmonic distortion and SNR as called out in the manufacturer datasheet. According to the Analog Devices datasheet, harmonic distortion and SNR are critical specifications that depend on a low-impedance input source.

The device includes an internal 2.5 V reference with a typical temperature drift of ±10 ppm/°C, and an external reference input that can be driven up to 3 V. The ADC provides a 4-wire serial interface (CS, SCLK, DIN, DOUT) and supports daisy-chaining for multiple devices. The operating temperature range is -40°C to +125°C, making it suitable for harsh environments. Typical applications for the AD7327BRUZ include industrial process control, data acquisition systems, motor control, and power monitoring. Its true bipolar input capability and software-selectable ranges make it ideal for interfacing with sensors that produce bipolar signals, such as current transformers and thermocouples. The high throughput and 13-bit resolution enable precise measurement in real-time control loops. When designing with the AD7327BRUZ, ensure that the analog input signals are within the selected input range to avoid damage. Use a low-impedance source and proper decoupling on the AVDD and DVDD pins. The reference input should be bypassed with a 10 µF capacitor for stable operation. The serial interface timing must comply with the datasheet specifications to ensure reliable data transfer.

AD7327TRU-EP - 12-Bit+Sign Bipolar 8-Ch SAR ADC | Analog Devices

The Analog Devices AD7327TRU-EP is a 12-bit plus sign successive-approximation analog-to-digital converter (SAR ADC) with eight analog input channels and software-selectable true bipolar input ranges of +/-10 V, +/-5 V, +/-2.5 V, and 0 V to +10 V. Housed in a 20-lead TSSOP package and specified for the military -55C to +125C temperature range, this enhanced-product (EP) variant supports defense and aerospace applications by providing a controlled manufacturing baseline, one assembly/test site, one fabrication site, enhanced product change notification, and qualification data on request. The device is identified by DSCC Drawing Number V62/14636 and is qualified per the AQEC standard. An SAR ADC is a type of analog-to-digital converter that uses a successive-approximation register to perform a binary search across the input voltage, producing one bit per clock cycle. Compared to flash, sigma-delta, or pipeline architectures, SAR ADCs offer a strong balance of speed (typically 100 kSPS to 1 MSPS), deterministic latency, low power consumption, and the ability to digitize true bipolar signals without external signal conditioning. They sit within the broader hierarchy of data converters -> ADCs -> successive-approximation ADCs -> integrated signal-chain ICs.

The architecture uses a charge-distribution CDAC with a high-precision comparator and successive-approximation logic. Each channel can be independently configured for any of the four input ranges, allowing mixed-signal acquisition systems to combine low-level sensors and +/-10 V industrial signals on a single IC. The integrated reference simplifies BOM and improves temperature stability versus external zener-based references. Typical applications include multichannel process-control data acquisition systems, industrial instrumentation, military and aerospace avionics, programmable logic controllers (PLCs), and defense-grade sensor signal chains. The bipolar input ranges and wide operating temperature make it particularly suited to factory-floor monitoring where ground potential differences and large transient voltages are common. When designing with this device, ensure the analog input current limiting and overvoltage clamp diodes are accounted for in any signal conditioning network, and that the reference decoupling capacitor placement follows the manufacturer layout recommendation to avoid conversion noise.

AD7327TRU-EP-RL7 - 12-Bit+Sign 500kSPS 8-Ch ADC | Analog Devices

The Analog Devices AD7327TRU-EP-RL7 is an 8-channel, software-selectable, true bipolar input, 12-bit plus sign successive-approximation analog-to-digital converter (SAR ADC) housed in a 20-pin TSSOP (RU) package, supplied on a 7-inch reel. It samples at up to 500 kSPS, supports a serial SPI/DSP-compatible interface, and accepts 2, 3, or 4 analog inputs in single-ended, differential, or pseudo-differential configuration.

A SAR (Successive-Approximation Register) ADC is a type of data converter that resolves a single analog sample by performing one conversion decision per clock cycle against an internal precision DAC and comparator, then delivering a fully settled digital code within N cycles for an N-bit output. SAR ADCs sit within the broader hierarchy of analog-to-digital converter -> data converter -> mixed-signal IC -> semiconductor, and are favored for applications that demand low latency, deterministic throughput, and DC precision without the pipeline delay of higher-speed flash or pipelined architectures. Key features of the AD7327TRU-EP-RL7 include software-selectable input ranges of ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V on every channel, true bipolar operation on each input, an external reference option via the REFIN/OUT pin that extends the input range to ±12 V when a 3 V reference is applied, an integrated 8-channel MUX with simultaneous sample-and-hold in a 1:1 S/H-to-ADC ratio, and a sequencer that simplifies multi-channel scanning. The device operates from a 2.7 V to 5.25 V digital supply and ±12 V to ±16.5 V analog supplies, drawing typical power in the low-mA range, and includes software-configurable output coding in two's complement, straight binary, or sign-magnitude formats. The AD7327-EP is implemented on Analog Devices' iCMOS (industrial CMOS) process technology, which combines high-voltage bipolar transistors with sub-micron CMOS to deliver true bipolar ±10 V or higher input swings on a single 5 V supply. This process allows the converter to be used directly at industrial signal levels without external signal conditioning or level shifting, while keeping power and package size compact for space-constrained designs. Typical applications include industrial process control and PLC analog input modules, multichannel data acquisition front ends, defense and aerospace signal conditioning, motor control current/voltage monitoring, and any system requiring true bipolar measurement on multiple channels with deterministic throughput. The wide bipolar input range, channel-by-channel software configurability, and -EP qualification make the part particularly suited to ruggedized multi-channel measurement. When designing with this device, ensure the analog and digital supplies are decoupled close to the pins with a 0.1 µF and 10 µF combination, sequence the analog supply before or simultaneously with the digital supply to avoid latch-up, and configure the input range register per channel before initiating conversion.

AD73322ARZ

AD73322ARZ - Dual 16-Bit AFE, 73mW, 28-SOIC | Analog Devices

The Analog Devices AD73322ARZ is a dual, 16-bit analog front-end (AFE) processor for general-purpose speech and telephony applications, packaged in a 28-lead SOIC (300 mil). It integrates two 16-bit A/D conversion channels and two 16-bit D/A conversion channels, each delivering 77 dB SNR over a voiceband signal bandwidth, with typical total power consumption of 73 mW. An analog front-end (AFE) is a mixed-signal subsystem that bridges analog transducers (microphones, speakers, line interfaces) and a digital signal processor (DSP). In the signal chain, an AFE sits between the sensor and the host processor, performing sampling, reconstruction, anti-alias filtering, and gain conditioning. The AD73322 specifically belongs to the broader class of programmable voice-band codecs (analog-to-digital converter plus digital-to-analog converter plus filtering in one chip), positioned hierarchically as AFE -> mixed-signal IC -> data converter -> signal conditioning IC -> semiconductor. Common synonyms include "voice codec", "audio codec", and "DSP front-end". Key features of the AD73322ARZ include a programmable sampling rate (8 kSPS, 16 kSPS, 32 kSPS, 64 kSPS) derived from an internal master clock, an 8 kHz to 64 kHz sample-rate range, a serial port (SPORT) with rates programmable to match slow or fast DSP engines, and an on-chip voltage reference (REFCAP, 2.4 V when 5VEN=1). The 5VEN pin allows operation from either 3 V or 5 V supplies. The device supports daisy-chained (cascaded) operation of multiple AD73322 units to increase channel count without consuming additional DSP serial ports. ADI quotes 77 dB SNR for both ADC and DAC channels across voiceband bandwidth, with low total harmonic distortion suitable for full-duplex speech paths. Typical applications include voice-over-IP (VoIP) handsets, speech recognition front-ends, modem analog front-ends, audio recording/playback subsystems, and industrial two-way intercoms. The wide DSP compatibility and cascadable architecture also make it useful in conference phones and call-center headset bases. When designing with this part, note that the part dissipates approximately 73 mW at 3 V operation; provide a small copper pour on the SOIC exposed area and keep digital switching noise away from the AGND plane to preserve the 77 dB SNR figure.

AD734ANZ - 10MHz 4-Quadrant Analog Multiplier/Divider | ADI

The Analog Devices AD734ANZ is an accurate, high-speed 4-quadrant analog multiplier and divider that delivers 10 MHz full-power bandwidth, a 450 V/µs slew rate, and ±0.1% typical multiplication error in a 14-pin PDIP (N-14) through-hole package. Its transfer function is W = (XY)/U, where X, Y, and U are differential voltage inputs and W is the low-impedance voltage output capable of swinging 20 V peak-to-peak into a load. An analog multiplier is a fundamental signal-processing building block that performs real-time multiplication of two continuous-time analog signals, and is used as the core cell inside gain-controlled amplifiers, modulators, RMS-to-DC converters, squarers, frequency doublers, and dividers. Multipliers are a sub-category of analog computational ICs alongside log/antilog amplifiers, true-RMS converters, and analog multipliers/dividers, all of which sit within the broader signal-conditioning and data-conversion hierarchy. The 4-quadrant designation means that the inputs X, Y, and U may each be positive or negative, and the output W may therefore be positive or negative, enabling two-polarity signal processing without external offset shifting. Key features of the AD734ANZ include pin-compatibility with the legacy industry-standard AD534, on-board thin-film laser-trimmed resistors that yield 0.1% typical accuracy without user adjustment, differential X, Y, and U inputs with high common-mode rejection, a low-impedance output capable of driving heavy loads, and a 200 ns settling time to 0.1% at full power. The supply range of ±8 V to ±16.5 V makes it suitable for both ±12 V industrial systems and ±15 V instrumentation rails. The AD734's architecture is built around three translinear cells and a high-gain output op amp, with on-chip laser-trimmed thin-film resistors that eliminate the external gain-setting components required by older multipliers such as the AD534. The low-impedance output stage can deliver full 20 V p-p directly into low-impedance loads, removing the need for an external buffer in most applications. Compared with the AD633 and MPY634, the AD734 is materially faster (10 MHz vs ~1 MHz) and supports a true divider mode through its U input. Typical applications include high-speed precision multipliers, dividers, and squarers in instrumentation; voltage-controlled amplifiers (VCAs) and automatic gain control (AGC) loops in audio and RF; balanced modulators and demodulators in communications; true-RMS converters when paired with a squaring circuit; and waveform generators. The wide bandwidth also makes it suitable for adaptive filters and real-time signal-conditioning blocks. When designing with the AD734ANZ, observe the supply-rail decoupling guidelines: place 100 nF ceramic capacitors as close as possible to both supply pins and use bulk decoupling on the analog rails. The U input (denominator) must remain inside its linear input range (typically ±10 V) to avoid divider saturation; unused inputs should be tied to a defined voltage (typically ground) rather than left floating.

AD7366BRUZ-5500RL7 - 12-Bit Dual 1MSPS Bipolar SAR ADC | ADI

The Analog Devices AD7366BRUZ-5500RL7 is a dual, 12-bit, 1 MSPS, true bipolar input, simultaneous-sampling successive approximation register (SAR) analog-to-digital converter housed in a 24-lead TSSOP (RU-24) package. The part operates from a single 2.5 V analog supply (with 2.5 V or 3.3 V digital I/O supply), accepts true bipolar differential or single-ended inputs of ±5 V, ±10 V, 0 V to 5 V or 0 V to 10 V through the on-chip input scaler, and produces 12-bit conversion results through an SPI/QSPI/MICROWIRE/DSP-compatible serial interface at speeds up to 1 MSPS. SAR ADCs are a class of analog-to-digital converters that use a binary-search successive-approximation algorithm with an internal capacitive DAC and a single comparator. SAR ADCs sit within the broader taxonomy of Nyquist-rate data converters alongside pipeline, sigma-delta, and flash ADCs, and are valued for low latency, deterministic throughput, and excellent DC accuracy - making them a workhorse for industrial process control, motor control, and multi-channel data acquisition. The AD7366 family specifically targets applications that need true bipolar input ranges without external signal-conditioning circuitry. Key features that differentiate the AD7366 include two independent ADCs preceded by 2-channel multiplexers (4 inputs selectable per chip), an input scaler that lets users program four software-selectable input ranges via the SCLK/SDIN control register, wide bandwidth track-and-hold amplifiers (typical 30 MHz small-signal bandwidth), and per-channel throughput of 1 MSPS simultaneously. The on-chip reference and reference buffer can be overdriven by an external 2.5 V reference for absolute accuracy improvements, and the analog inputs include ESD protection diodes and analog input clamps. Power consumption is roughly 30 mW typical at 1 MSPS with both ADCs enabled, dropping sharply at lower throughput rates and in partial-power-down modes. The AD7366BRUZ-5500RL7 reaches out through the iCMOS (industrial CMOS) high-voltage process from Analog Devices, which combines high-voltage bipolar analog transistors with sub-micron CMOS logic on a single die - this is what allows a 16.5 V tolerant input stage to coexist on a 12-bit SAR converter IC. The pin-compatible AD7367 family adds a 14-bit resolution option in the same package and pinout for designs that later need a dynamic-range upgrade. Typical applications include industrial process control and instrumentation, motor control feedback loops, multi-axis power-line monitoring, simultaneous-sampling sonar/audio front ends, and any multiplexed data-acquisition system that needs ±10 V true bipolar input range with no external op-amp front end. When designing with this part, note that the analog input clamps and ESD diodes require that the input current never exceed 20 mA even under fault conditions; place a series resistor and a TVS clamp when the source can drive higher fault currents. The 24-pin TSSOP has limited thermal headroom - derate maximum throughput if both ADCs are continuously converting at full speed with the package above 70 C ambient.

AD736JRZ-R7 - True RMS-to-DC Converter SOIC-8 | Analog Devices

The Analog Devices AD736JRZ-R7 is a low cost, low power, precision true RMS-to-DC converter in an 8-pin SOIC package, converting an AC voltage waveform to a DC output equal to the true RMS value, with a 200 mV rms full-scale input range and laser-trimmed accuracy of ±0.3 mV ±0.3% of reading for sine wave inputs. A true RMS-to-DC converter is a specialized analog signal-conditioning IC that computes the root-mean-square of an input waveform in real time, producing a DC voltage that corresponds to the effective power of the signal regardless of waveform shape. It sits within the broader hierarchy of AC/DC measurement devices: sensor -> amplifier -> RMS-to-DC converter -> ADC or panel meter. Unlike average-responding rectifiers, which are accurate only for pure sine waves, a true RMS converter correctly handles distorted, pulsed, and noise-like signals. Key features of the AD736 include a 200 mV rms full-scale input range (extendable for larger inputs with an external input attenuator), very high input impedance of 10^12 ohms, and a low input bias current of 25 pA maximum, which together minimize loading of high-impedance sources. The device can also be configured to output the average rectified value or the absolute value of the input, adding measurement flexibility. Technically, the AD736 is a monolithic, laser-trimmed IC that computes RMS via explicit squaring and division of the input signal followed by low-pass filtering. Its low power consumption of approximately 200 uA from supplies up to 12 V makes it well suited to battery-powered instruments, while signal bandwidth up to the 190 kHz / 460 kHz class keeps it useful for audio and industrial-frequency measurements. Typical applications include handheld multimeters and DMM AC ranges, power monitoring in industrial equipment, audio loudness and sound-level measurement, and upgrading non-RMS precision rectifier circuits, where the AD736 offers higher accuracy at equal or lower cost. Design consideration: the averaging capacitor on the CU pin sets low-frequency accuracy and settling time; use a larger capacitor for low-frequency inputs and expect ripple and settling trade-offs at the lowest frequencies.
