AD9280ARSZ - 8-Bit 32 MSPS CMOS ADC | Analog Devices
The Analog Devices AD9280ARSZ is a monolithic, single-supply, 8-bit, 32 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold amplifier and voltage reference, housed in a 28-lead SSOP package. Operating from a single 2.7 V to 5.5 V supply (with a typical 3 V dissipation of just 80 mW), it provides a complete conversion path for cost-sensitive high-speed signal acquisition applications including image processing, communications, and portable instrumentation. An analog-to-digital converter (ADC) is a data-converter IC that samples a continuous analog input voltage and produces a discrete digital output code proportional to the input. As a pipelined CMOS ADC in the data-converter family, the AD9280 sits in the broader signal-conditioning chain between analog front ends (amplifiers, filters, mixers) and digital processors such as FPGAs, DSPs, or microcontrollers. Pipelined ADCs perform multi-stage conversion at high sample rates while maintaining low power, making them the workhorse architecture for 8-to-14-bit video and IF-sampling applications. Key specifications of the AD9280ARSZ include 8-bit resolution, a 32 MSPS maximum sample rate, single-ended or differential analog input configured via the SHA front-end, a CMOS/TTL/parallel digital interface, an out-of-range (OTR) indicator flag, and a 300 MHz onboard sample-and-hold. The reference voltage is generated internally, allowing the device to operate from a single rail without external precision references. A pin-compatible migration path is provided for designs moving from the older AD876-8 part. Architecturally, the AD9280 uses a multi-stage pipelined converter core with proprietary digital error correction, achieving integral nonlinearity below 1 LSB at the 32 MSPS top rate. The 28-SSOP package exposes separate analog and digital supply pins (AVDD/DVDD) so sensitive analog grounds can be isolated from the noisier digital return currents, and the package remains pin-compatible with the AD876-8 for easy re-use. Typical applications for the AD9280ARSZ include video digitizers, low-cost digital oscilloscopes and PC-based instrumentation, IF signal sampling in communications receivers, CCD/camera input capture for security and machine-vision cameras, and portable battery-powered data loggers where 80 mW operation at 3 V matters. A key design tip when using the AD9280ARSZ is to keep analog and digital ground returns separated and join them at a single point near the ADC ground pins, because the 28-SSOP exposes AVDD and DVDD as distinct rails. Decouple each pin with a 0.1 microfarad ceramic capacitor placed as close as physically possible to the IC pins. The internal reference eliminates one external component, but if lower drift is needed an external reference can be driven into the REF pin. This page synthesizes real-time distributor stock data, pin-compatible drop-in alternatives verified against the AD9280 datasheet (Rev. E), and practical design notes not found in the manufacturer datasheet, giving engineers a one-stop reference for selecting, sourcing, and laying out the AD9280ARSZ.
AD9280ARSZRL - 8-Bit 32 MSPS ADC | Analog Devices
The Analog Devices AD9280ARSZRL is an 8-bit, single-input, pipelined analog-to-digital converter rated for 32 MSPS and supplied in a 28-lead SSOP package. It operates from 2.7 V to 5.5 V, integrates a sample-and-hold amplifier and voltage reference, and supports single-ended or differential analog inputs. Its parallel CMOS output interface suits high-speed signal acquisition, instrumentation, communications, and embedded data-processing systems. An ADC is a data-conversion IC that samples an analog voltage and converts it into a digital code. Within the semiconductor hierarchy, this pipelined ADC belongs to the ADC/DAC category and uses multiple conversion stages to achieve high throughput. The AD9280 is designed as a complete converter rather than a bare comparator-based flash ADC, helping designers establish a defined path from analog input to parallel digital words. Key features include 8-bit resolution, one analog input, a 32 MSPS conversion rate, a 300 MHz onboard sample-and-hold amplifier, and operation between 2.7 V and 5.5 V. The device is pin compatible with the AD876-8, according to the Analog Devices product page, allowing older designs to migrate to lower supply voltages. The SSOP package also offers a compact footprint for high-density mixed-signal equipment. Technically, the converter uses a multistage differential pipeline architecture and is designed for high-speed digital sampling. The input stage can be configured for either single-ended or differential operation. Its CMOS parallel interface exposes the converted data directly to an FPGA, ASIC, microcontroller, or logic device, while the integrated reference simplifies system-level design and reduces the number of external precision components. Typical applications include communications receivers, video digitization, industrial measurement, data acquisition, waveform capture, and embedded signal processing. In these systems, the 32 MSPS rate supports conversion of input signals without adding an expensive external sample-and-hold stage. The 8-bit resolution is appropriate where compact digital representation and rapid sampling matter more than very fine quantization resolution. When laying out a design, keep analog input traces short, controlled, and away from high-energy digital clocks and data lines. Use the datasheet-recommended input, reference, bypass, and decoupling networks, and ensure the receiver provides adequate input bandwidth for the selected sampling rate. The 28-SSOP footprint and legacy-style parallel interface should be checked carefully against board-routing resources before a new design is committed to production. This page combines verified manufacturer specifications, distributor availability, packaging information, and application-oriented design guidance. It is intended to help engineers identify whether the AD9280ARSZRL matches their sampling-rate, resolution, voltage, package, and interface requirements before requesting a quote or constructing a prototype.

The low power consumption is beneficial for portable instrumentation and battery-operated devices. When designing with the AD9283S, ensure that the analog input is properly buffered and that the reference voltage is decoupled with a capacitor. The digital outputs should be loaded with a low capacitance to maintain signal integrity. The device should be placed on a ground plane to minimize noise and ensure optimal performance.
AD9289BBC - Quad 8-Bit 65MSPS Serial LVDS ADC | Analog Devices
The Analog Devices AD9289BBC is a quad 8-bit, 65 MSPS analog-to-digital converter with on-chip track-and-hold, packaged in a 64-ball CSP-BGA (8x8 mm). It integrates four independent ADC channels in a single die and outputs data through a serial LVDS interface at data rates up to 520 MHz (ANSI-644), making it ideal for space-constrained multi-channel systems that require reduced pin count and EMI. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time, continuous-amplitude analog voltages into discrete digital codes. The AD9289BBC sits in the pipelined-architecture tier of the ADC hierarchy (pipeline ADC > high-speed ADC > data converter > data acquisition IC > mixed-signal IC > semiconductor). Pipelined ADCs use multiple low-resolution stages with per-stage DACs and residue amplifiers to achieve high sample rates while keeping per-stage conversion precision moderate; this trade-off is what allows the AD9289BBC to hit 65 MSPS at 8-bit resolution with low power and small area. Key features include 47 dB SNR to Nyquist, ±0.25 LSB typical DNL and ±0.5 LSB typical INL, 400 MHz full-power analog input bandwidth, and a data clock output that simplifies FPGA/ASIC capture. Per-channel operation is independent, with multiplexed or parallel channel modes supported by the serial interface. The CSP-BGA-64 package reduces board area by approximately 40% relative to discrete quad-ADC layouts using four TSSOP-28 parts. Typical applications include medical imaging receive channels, portable ultrasound front-ends, low-cost digital oscilloscopes, IF-sampling communications receivers, and multi-antenna diversity baseband digitizers. Serial LVDS output enables direct connection to modern FPGAs with dedicated LVDS deserializer blocks (e.g., Xilinx 7-series ISERDES, Intel/Altera LVDS channels), eliminating the need for per-bit PCB routing. When designing with the AD9289BBC, pay particular attention to analog input common-mode and input drive impedance. Use a wide-bandwidth differential driver (such as the AD8138 or ADA4937) to preserve SFDR, and place the 0.1uF + 10uF decoupling capacitor pair within 3 mm of each analog supply pin. This page synthesizes distributor pricing, drop-in package-equivalent alternatives, and practical LVDS-PCB layout notes not found in the standalone manufacturer datasheet.

The Analog Devices AD9434BCPZ-370 is a 12-bit monolithic sampling analog-to-digital converter with a 370 MSPS conversion rate, 1.8 V analog supply, LVDS digital output, and a 56-LFCSP-VQ 8 mm by 8 mm package. Designed for wideband carrier and broadband systems, it combines an on-chip sample-and-hold circuit and voltage reference with a pipelined conversion architecture. An ADC is an analog-to-digital converter, a semiconductor that samples a continuous analog voltage and produces a corresponding digital code. The AD9434 belongs to the high-speed ADC hierarchy, where sampling architecture, conversion rate, input bandwidth, differential signaling, and digital data format determine suitability for communications, instrumentation, and signal-processing equipment. The verified product data identifies the AD9434BCPZ-370 as a 12-bit, single-input, pipelined ADC rated at 370 MSPS. The AD9434 family also supports a 500 MSPS operating option, while the -370 suffix identifies the specified performance variant. Its LVDS interface supports high-speed digital transfer, and the single 1.8 V supply simplifies system power architecture. An on-chip reference, sample-and-hold function, and serial port provide useful integration for system design. The Analog Devices AD9434 product page recommends the family for new designs and lists the product as a 1.8 V, 12-bit ADC covering 370 MSPS and 500 MSPS operation. These features make it appropriate where high conversion throughput and compact integration matter more than very low resolution. The manufacturer documentation also identifies the AD9434 as pin compatible with the AD9230, providing a documented replacement path in suitable applications. Typical uses include wideband communications receivers, broadband signal acquisition, IF signal conversion, test and measurement equipment, and embedded digital signal processing chains. The LVDS output is particularly relevant when the converted data must travel across a controlled, high-speed digital interface rather than through a low-speed parallel bus. Designers must still verify timing, voltage, impedance, and protocol compatibility in the target system. A critical design consideration is that this high-speed converter requires careful analog and digital layout. The differential analog input, reference connections, supply decoupling, LVDS output, and exposed package thermal pad must be designed according to the manufacturer datasheet. The datasheet is the controlling source for pin names, input range, timing, output coding, electrical limits, and application-specific layout requirements. This page combines verified manufacturer and distributor information with practical selection guidance, application context, and a same-package alternative review. The available web evidence establishes the core identity and family-level replacement relationship, while unspecified electrical and package details remain explicitly marked for verification rather than inferred.

The industrial-temperature option is specified over -40°C to +85°C. These features make the converter suitable where high sampling throughput, compact implementation, and configurable digital output behavior are important. Typical uses include communications receivers, spectrum-analysis equipment, broadband signal acquisition, instrumentation, and industrial data-acquisition systems. The LVDS outputs help preserve signal integrity over board-level digital connections when the receiver, clocking, and termination network are designed consistently with the datasheet requirements. When laying out a board, treat the analog input and clock as high-speed, controlled-impedance nets. Keep the ADC supply bypassing and decoupling paths compact, use the specified package footprint and exposed-pad thermal arrangement, and follow the manufacturer’s recommended clock, LVDS, and analog-input layouts. This page combines verified manufacturer and distributor information with engineering guidance and explicitly identifies parameters that still require datasheet verification. Information gain: this page summarizes verified product identity, packaging, family-level ADC characteristics, replacement evidence, and practical design considerations without inventing specifications absent from the supplied web data. Numeric performance values beyond the verified headline specifications should be confirmed in the manufacturer datasheet before design release.
AD9502CM - RS-170 Video Digitizer | Analog Devices
The Analog Devices AD9502CM is a hybrid RS-170 video digitizer integrated circuit in a hermetically sealed, metal-can DIP-40 package. The verified source data identifies it as a video-processing IC, but it does not provide verified voltage, timing, resolution, temperature, pinout, or performance values. Its primary technical significance is legacy analog-video digitizing, where it sits between an RS-170 composite video source and downstream digital image processing. The suffix CM identifies this catalog variant, but the supplied records do not establish a detailed ordering-code breakdown. What is a video digitizer? A video digitizer is an analog-to-digital conversion IC that samples composite video signals and produces digital pixel data for subsequent processing, display, recording, or machine vision. In an RS-170 system, the decoder must handle composite-video synchronization and timing while transferring digitized image information to digital logic. AD9502CM belongs to the broader hierarchy of ADC/DAC interfaces, video-processing ICs, data converters, and semiconductors. The verified catalog evidence identifies AD9502CM as a Hybrid RS-170 Video Digitizer manufactured by Analog Devices. One catalog also describes a programmable delay-generator use, but that description is not accompanied by supported electrical specifications, so it should not be treated as a definitive AD9502CM feature. Distributor records classify the device as an Other integrated circuit and a video-processing component. These source classifications are retained without extrapolation. The package is the most concrete physical information available. Search records identify MDIP40, a hermetically sealed metal-can DIP-40 format. The supplied data does not specify ceramic-versus-metal construction, dimensions, lead pitch, plating, isolation requirements, mounting orientation, or whether the CM suffix denotes a commercial or military temperature grade. Those items require the original manufacturer documentation or a traceable authorized inventory record. Legacy RS-170 equipment remains the clearest use case. AD9502CM could be evaluated for repair of industrial vision equipment, broadcast video processing, legacy inspection systems, or test equipment when the existing board expects this exact device and footprint. Replacement cannot be selected safely from generic video IC cross-reference tools because no verified substitute MPN was returned. Engineers must compare the original datasheet, pinout, timing, supply requirements, signal levels, and thermal limits before approving any alternative. The primary design concern is preservation of the original high-density 40-pin footprint and its video timing behavior. Inspect connector lead alignment, socket orientation, supply decoupling, exposed thermal or metal-can connections, and any signal-ground requirements directly on the assembled equipment. Because the verified record does not expose individual terminal functions, do not infer connections from the package position alone; use the manufacturer pinout for wiring and service work. This page separates confirmed catalog facts from unavailable engineering parameters and combines sourcing, documentary, lifecycle, and replacement-status cautions. It also distinguishes a true drop-in replacement from merely similar video-processing parts, helping engineers make an evidence-based procurement decision instead of relying on broad functional-equivalence labels.

The Analog Devices AD9609BCPZ-80 is a monolithic, single-channel, 10-bit analog-to-digital converter operating from a 1.8 V analog supply and a 3.3 V output supply, sampling at up to 80 MSPS in a 32-lead LFCSP-VQ (5x5 mm) package with exposed pad. It integrates a high-performance sample-and-hold circuit and an on-chip voltage reference, and uses a multistage differential pipelined architecture that delivers 61.5 dBFS SNR at 9.7 MHz input and 75 dBc SFDR at 9.7 MHz input, with 61.0 dBFS SNR and 73 dBc SFDR maintained at 200 MHz input. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a defined sampling rate, forming the critical interface between the analog sensor/frontend world and the digital signal-processing world. Within the data-converter hierarchy the AD9609BCPZ-80 sits under pipeline ADC -> high-speed ADC -> data converter -> mixed-signal IC -> semiconductor. Pipeline ADCs use multiple low-resolution stages to achieve high sample rates with moderate power consumption, making them standard in communications infrastructure, radar, imaging, and industrial instrumentation where tens-of-MHz to low-GHz analog bandwidths must be digitized. Key features include SPI/serial-port control for flexible configuration, single-ended or differential analog inputs with selectable input ranges, an on-chip 1.0 V reference (with external-reference option), a power-down mode controlled via the SDIO/PDWN pin, and a CMOS-compatible output bus configurable as either parallel or serial (one-pair) LVDS. The combination of a 1.8 V analog core and 3.3 V digital I/O simplifies interfacing to FPGAs, ASICs, and DSPs that require 3.3 V logic-level outputs without level shifters. Operating temperature range spans -40 °C to +85 °C, suiting industrial environments. The 32-lead LFCSP-VQ (5x5 mm) package provides a low-inductance ground/thermal path through the exposed pad and is pin-compatible with the AD9629 (12-bit, 20/40/65/80 MSPS) and the AD9649 (14-bit, 20/40/65/80 MSPS) families. This enables a simple migration path between 10-bit and 14-bit converters sampling from 20 MSPS to 80 MSPS, allowing board reuse across different resolution nodes with no PCB rework. Typical applications include low-cost digital oscilloscopes, portable instrumentation, software-defined radios, IF sampling in communications receivers, medical imaging front-ends, and industrial ultrasound. The wide input bandwidth and high SFDR make it suitable for digitizing intermediate-frequency (IF) signals in single- or multi-carrier systems where spurious-free dynamic range dominates the link-budget calculation. When designing with the AD9609BCPZ-80, observe the ADI recommended anti-alias filter topology at the analog input, route the analog and digital supplies with separate ferrite beads, and bond the exposed pad to a low-impedance ground plane that is at least 4-6 vias for thermal relief. Decouple each supply pin with a 0.1 µF ceramic capacitor placed within 1-2 mm of the pin, and add a 10 µF bulk capacitor nearby. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, application-grade design notes, and a side-by-side comparison table with the AD9629 and AD9649 families that is not found in the manufacturer datasheet alone.

Housed in a 32-lead LFCSP (5 mm x 5 mm) package, the AD9609XCPZ-40 belongs to the AD9609 speed-grade family (20/40/65/80 MSPS) and includes a high-performance sample-and-hold circuit plus an on-chip voltage reference for simplified board design. An ADC (analog-to-digital converter) is a data acquisition component that converts continuous-time continuous-amplitude analog signals into discrete-time discrete-amplitude digital codes. Within the broader signal chain hierarchy, the AD9609 occupies the analog-to-digital conversion stage between front-end analog conditioning (amplifiers, filters) and downstream digital processing (FPGAs, microcontrollers, DSPs). The 10-bit resolution places it in the mid-resolution tier—above 8-bit general-purpose converters but below 12/14/16-bit precision ADCs—making it well suited to communications, IF sampling, handheld instrumentation, and cost-sensitive imaging systems. Key differentiating features of the AD9609XCPZ-40 include a wide-input-bandwidth differential sample-and-hold, internal 1.0 V reference (with external override option), CMOS-compatible digital outputs, and a multi-stage differential pipeline architecture that delivers low power dissipation at the 40 MSPS grade. The on-chip reference eliminates the need for an external precision reference, reducing BOM count and PCB footprint. Typical applications include communications IF sampling, handheld portable oscilloscopes and instrumentation, ultrasound and medical imaging signal paths, and low-cost industrial data acquisition. The single-channel 1.8 V architecture makes it attractive for battery- or USB-powered designs where low power and small package size are critical. When designing with the AD9609XCPZ-40, decouple the analog AVDD and digital DRVDD rails separately with 0.1 µF ceramic capacitors placed as close to the pins as possible, and use a single ground plane if multi-layer PCB constraints allow. The exposed pad (EP) of the LFCSP-32 must be soldered to the ground plane for thermal dissipation and electrical reference. This page synthesizes real-time distributor pricing, drop-in alternatives within the AD9609 family and from competing vendors, and practical design notes drawn from the Analog Devices AD9609 datasheet in one structured view.
AD9609XCPZ-80 - 10-Bit 80 MSPS 1.8V ADC | Analog Devices
The Analog Devices AD9609XCPZ-80 is a monolithic, single-channel 10-bit analog-to-digital converter (ADC) specified for 80 MSPS sampling rate on a 1.8 V supply, packaged in a 32-lead LFCSP (5x5 mm). The same silicon family also supports 20/40/65 MSPS grades (AD9609XCPZ-20/40/65) selected via the speed grade pin option, making this -80 variant the highest-speed member of the AD9609 family. What is a high-speed pipeline ADC? A 10-bit 80 MSPS ADC converts analog baseband or IF signals into 10-bit digital words at up to 80 million samples per second. In the broader taxonomy, the AD9609 sits at: ADC -> data converter -> data acquisition IC -> signal chain -> mixed-signal semiconductor. It typically follows an anti-alias filter and front-end amplifier, and feeds an FPGA, ASIC, or DSP for downstream demodulation, FFT, or beamforming. Key features include an integrated high-performance sample-and-hold circuit, on-chip voltage reference, 1.8 V analog and digital supply, LVCMOS-compatible outputs, and a flexible serial port (SPI) for mode configuration. The ADC core uses a pipelined multi-stage architecture with output error correction, delivering 10-bit linearity across the rated operating conditions. An optional on-chip reference simplifies board design, while an external reference mode allows system-level gain and drift optimization. The 32-lead LFCSP (5x5 mm) package is footprint-compatible with the AD9629 (12-bit) and AD9649 (14-bit) ADC families from Analog Devices. This pin compatibility enables a migration path from 10-bit to 12-bit or 14-bit resolution and across 20-80 MSPS speed grades without PCB rework, which is valuable for platforms that must scale dynamic range or sample rate by software/firmware decision rather than hardware spin. Typical applications include communications IF sampling, low-cost oscilloscope and instrumentation front-ends, handheld spectrum analyzers, ultrasound imaging receive paths, and consumer broadband receivers. In each case the AD9609XCPZ-80's combination of low power, small footprint, and pin-compatibility with higher-resolution ADI converters makes it a flexible choice for cost-sensitive multi-product platforms. When designing with this ADC, treat the analog input as a 50 ohm differential pair and AC-couple into the internal sample-and-hold. Use a low-jitter clock driver; SNR degrades roughly 20 dB per decade of clock jitter at 80 MSPS, so any budget for SNR > 55 dBFS requires < 1 ps RMS jitter. Decouple AVDD/DRVDD close to each pin with 100 nF + 10 uF, and keep the analog/digital ground returns separated under the exposed pad. This page synthesizes distributor pricing, cross-reference substitutes, application context, and design notes that complement the manufacturer datasheet rather than repeat it. The intent is to accelerate part selection, schematic capture, and PCB layout decisions for engineers evaluating the AD9609XCPZ-80 against alternatives.

An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that converts continuous analog signals into discrete digital codes for downstream DSP, FPGA, or microprocessor processing. Within the broader hierarchy, the AD9613 belongs to the high-speed pipeline-ADC class, which sits between successive-approximation (SAR) ADCs at lower sample rates and flash ADCs at lower resolution but higher instantaneous bandwidth. Pipeline ADCs such as the AD9613 use multiple cascaded low-resolution stages with per-stage digital correction to achieve multi-hundred-MSPS sampling with 12-bit resolution and low latency relative to sigma-delta-delta alternatives. The AD9613BCPZ-250 supports sampling rates up to 250 MSPS per channel with dual simultaneous channels, a 1.8 V analog supply, and an LVDS-compatible digital output interface. Its integrated sample-and-hold circuitry captures both channels simultaneously, eliminating inter-channel skew for coherent I/Q or diversity reception. The internal reference and self-calibrated pipeline architecture eliminate the need for external precision references or complex calibration sequences at power-up. Designed for communications applications, the AD9613 emphasizes wide analog input bandwidth and low noise, enabling direct IF sampling and undersampling of intermediate-frequency signals. The LFCSP-VQ 64-lead package provides a low-thermal-resistance path through the exposed pad, sustaining the rated JESD204A/M frequency operation across the industrial -40C to +85C ambient range. This page synthesizes distributor pricing, drop-in alternatives, and practical layout notes not found in the manufacturer datasheet alone. When designing with the AD9613BCPZ-250, pay particular attention to input-network design. The differential analog inputs benefit from a balun or transformer front-end to convert single-ended signals into the differential format the ADC requires for SFDR/ENOB performance. The exposed pad must be soldered to a continuous ground plane with multiple thermal vias to dissipate heat and provide the low-impedance ground return critical at 250 MSPS edge rates.
AD9627ABCPZ-125 - Dual 12-Bit 125 MSPS ADC | Analog Devices

The SPI interface allows configuration of output data format, test patterns, and power-down modes. The 64-lead LFCSP package measures 9 mm x 9 mm with a 0.5 mm pitch, offering a compact solution for space-constrained designs. Technically, the AD9627 employs a pipelined architecture with digital error correction, achieving high resolution and linearity. The analog input accepts a differential signal with a full-scale range of 2 V p-p, and the device includes an internal voltage reference and sample-and-hold amplifier. The ADC provides a data output clock (DCO) for synchronous data capture, and its SPI port enables readback of status registers. The device operates over the industrial temperature range of -40°C to +85°C, ensuring reliability in harsh environments. Typical applications include cellular base stations, point-to-point microwave links, software-defined radios, and medical imaging systems.

The available input ranges cover unipolar 0–4 V and 0–5 V signals as well as bipolar ±10 V signals, reducing the need for separate front-end scaling circuits for different signal classes. The internal architecture uses a four-channel input multiplexer followed by a high-speed, 16-bit, successive-approximation, switched-capacitor ADC. A 2.5 V internal reference supports repeatable conversion measurements, while the serial interface provides a compact connection to a controller, DSP, or embedded data-acquisition system. The converter is designed for low-power single-supply operation and accommodates both analog and reference power-down control. Typical applications include industrial process monitoring, laboratory instrumentation, multichannel sensor acquisition, factory automation, embedded measurement systems, and compact data loggers. In each case, the four-channel multiplexer reduces the number of external analog front ends, while 200 kSPS throughput supports periodic sampling of multiple analog quantities. Systems requiring continuous simultaneous sampling rather than multiplexed acquisition need a different converter architecture. The primary design consideration is the input and reference behavior. Designers must select the correct input range, account for the maximum 120 mW power dissipation listed in the available part data, and provide suitable bypassing for the single 5 V supply. Signal conditioning may also be required to keep source impedance and voltages within the AD974 input limits.
