AD9228BCPZ-40

AD9228BCPZ-40 - Quad 12-bit 40 MSPS Serial LVDS ADC | Analog Devices

The Analog Devices AD9228BCPZ-40 is a quad, 12-bit, 40 MSPS analog-to-digital converter (ADC) with four on-chip sample-and-hold circuits, housed in a 48-pin LFCSP-VQ (7x7 mm) package. It integrates four ADCs into a single device, consumes 119 mW per channel at 65 MSPS, and serializes the conversion data over ANSI-644 LVDS links for low-pin-count board routing. An ADC (analog-to-digital converter) is a semiconductor device that converts continuous-time analog signals into discrete digital codes at a defined sample rate. The AD9228 belongs to the pipelined ADC family within the broader data-converter category, sitting between sigma-delta (high-resolution, low-speed) and SAR (medium-resolution, high-speed) converters. Quad ADCs are used when multiple channels must be sampled simultaneously - typically in medical imaging, communications base stations, and multi-antenna receivers - because integrated quad parts reduce board area, BOM cost, and channel-to-channel timing skew versus four discrete ADCs. Key specifications include 70 dB SNR to Nyquist, 11.3-bit effective number of bits (ENOB), 82 dBc spurious-free dynamic range (SFDR) to Nyquist, ±0.3 LSB typical DNL and ±0.4 LSB typical INL. The -40 speed grade limits operation to 40 MSPS maximum; the higher-grade AD9228BCPZ-65 variant shares the same package and runs up to 65 MSPS. Programmable clock and data alignment plus built-in digital test pattern generation (deterministic, pseudo-random, and user-defined via SPI) simplify board bring-up and ATE test. Typical applications include medical ultrasound beamforming receivers, multi-channel communications IF digitization, portable instrumentation, and multi-antenna software-defined radio front ends. The 1.8 V analog supply and LVDS digital interface minimize EMI and ease interface to modern FPGAs such as the Xilinx 7-series and Intel Cyclone families. When designing with the AD9228, route analog inputs as 50 ohm differential pairs and place decoupling capacitors within 5 mm of each supply pin. Match trace lengths across the four channels when simultaneous sampling is required - the device's internal timing skew specification confirms the maximum acceptable mismatch budget.

AD9235BRURL7-40

AD9235BRURL7-40 - 12-Bit 40 MSPS 3V ADC | Analog Devices

The Analog Devices AD9235BRURL7-40 is a 12-bit, 40 MSPS, single 3 V supply, monolithic pipelined analog-to-digital converter housed in a 28-pin TSSOP (RU) surface-mount package. The device integrates a high-performance sample-and-hold amplifier (SHA), an internal voltage reference, and an on-chip duty-cycle stabilizer to maximize dynamic performance across varying input clock duty cycles. It is the 40 MSPS speed-grade variant within the broader AD9235 family, which also includes 20 MSPS and 65 MSPS versions. A pipelined ADC is a multi-stage converter architecture that processes samples in parallel sub-stages, achieving high sampling rates while keeping per-stage power dissipation low. Pipelined ADCs, in the broader ADC hierarchy, sit between successive-approximation-register (SAR) converters and flash converters, combining moderate resolution (typically 8-16 bits) with high throughput (tens to hundreds of MSPS). They are widely used in communications, instrumentation, and imaging applications where speed and resolution must be balanced against power and cost. Key features of the AD9235BRURL7-40 include a fully differential SHA input that supports user-selectable input ranges and offsets (single-ended or differential), an internal 2.5 V bandgap reference (external reference option available), CMOS-compatible digital outputs, and low power dissipation of approximately 110 mW at 40 MSPS with 3 V supply. The wide input bandwidth SHA handles multiplexed systems that switch full-scale voltage levels in successive channels and supports undersampling of IF signals well beyond the Nyquist rate. Operating temperature range spans -40°C to +85°C, making it suitable for industrial environments. Typical applications include communications IF sampling, portable and battery-powered imaging systems, multichannel multiplexed data acquisition, handheld oscilloscope front-ends, and cable-modem downstream receivers. The on-chip reference and small TSSOP footprint reduce external BOM, enabling compact designs. When using the internal reference, decouple REFT and REFB pins with high-quality ceramic capacitors; for best SFDR in multitone IF applications, the external reference mode is recommended.

AD9235BRURL7-65

AD9235BRURL7-65 - 12-Bit 65 MSPS ADC, 3V, TSSOP-28 | Analog Devices

The Analog Devices AD9235BRURL7-65 is a 12-bit, 65 MSPS pipelined analog-to-digital converter (ADC) operating from a single 3 V supply, housed in a 28-pin TSSOP package. It is a member of the AD9235 family that offers 20/40/65 MSPS speed grades, with this specific order code shipping in tape-and-reel packaging (the "RL7" suffix designates the 7-inch reel). The 65 MSPS variant provides a 70 dBFS SNR to Nyquist and 85 dBFS SFDR to Nyquist, supporting high-fidelity intermediate-frequency sampling in communication receivers. An ADC (analog-to-digital converter) is a semiconductor device that converts a continuous analog voltage into a discrete digital code at a sampling rate set by an external clock. Pipelined ADCs like the AD9235 use a multi-stage architecture that enables high sample rates at low power, while 12-bit resolution is the workhorse for cellular base stations, ultrasound imaging, and instrumentation. Within the broader taxonomy, the AD9235 sits in the data-converter category of mixed-signal ICs. Key features of the AD9235BRURL7-65 include a differential analog input with 500 MHz bandwidth, an on-chip sample-and-hold amplifier (SHA), an internal voltage reference, and ±0.4 LSB differential non-linearity (DNL). The analog input range scales from 1 V p-p to 2 V p-p, output data is available in offset-binary or twos-complement format, and an integrated clock-duty-cycle stabilizer (DCS) relaxes clock-source requirements. A proprietary front-end SHA driving the pipelined core allows IF-sampling well beyond the Nyquist limit, useful in undersampling radio receivers. Power consumption is 300 mW at 65 MSPS, and a flexible LVCMOS/TTL-compatible parallel digital interface simplifies FPGA/CPLD downstream connections. Typical applications include communications IF sampling, ultrasound and medical imaging front-ends, low-cost instrumentation, and high-speed data acquisition cards. Designers value the part when a low-power, single-supply 12-bit ADC in a compact surface-mount footprint is needed. When laying out the PCB, keep analog and digital grounds separated and join them at a single point near the ADC to limit return-path noise; place the input anti-alias filter as close as practical to the analog inputs and use a stable, low-jitter clock source to preserve SNR and SFDR.

AD9237BCPZ-20

AD9237BCPZ-20 - 12-Bit 20 MSPS ADC 3V Low Power LFCSP-32

The Analog Devices AD9237BCPZ-20 is a 12-bit, 20 MSPS monolithic analog-to-digital converter (ADC) that operates from a single 3 V supply in a 32-lead LFCSP-WQ (5x5 mm) package. It features an integrated high-performance sample-and-hold amplifier (SHA), an on-chip voltage reference, and selectable input ranges from 1 V p-p to 4 V p-p for flexible signal conditioning. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples continuous analog waveforms and converts them into discrete digital codes for downstream DSP, microcontrollers, or FPGAs. ADCs form a critical link in the signal chain between analog transducers (sensors, antennas, IF stages) and digital processors, and high-speed variants such as the AD9237 typically employ pipelined architectures for high sampling rates at moderate resolution. Within the broader taxonomy, the AD9237BCPZ-20 belongs to the family of pipeline ADCs, which sit between successive-approximation (SAR) ADCs (low-power, multi-MHz) and high-speed flash/serial-lvds ADCs (hundreds of MSPS). Key differentiating specifications include ultralow power dissipation at 20 MSPS, differential analog inputs with 500 MHz full-power bandwidth, and excellent dynamic performance that includes SNR of up to 66 dBc to Nyquist and SFDR of 80 dBc to Nyquist at 65 MSPS. The part also offers DNL of ±0.7 LSB, an output enable pin for multiplexing, and CMOS-compatible digital outputs. These specifications make it well suited for imaging, communications IF sampling, and portable instrumentation. Architecturally, the AD9237 uses a multistage differential pipelined topology with output error correction logic. The on-chip reference and SHA minimize external component count, while the selectable input-span feature allows direct coupling to a wide range of op-amp and transformer front ends without external attenuators. Typical applications include ultrasound and medical imaging front ends, communications IF sampling in software-defined radios, handheld test instruments, and low-power industrial data acquisition modules. Designers often select the AD9237BCPZ-20 when migrating from the pin-compatible AD9235 for additional speed headroom. A key design consideration is proper layout of the analog and digital grounds and the use of low-noise LDOs on the 3 V supply rail to preserve SNR. The output enable pin should be tied properly to avoid bus contention during multi-ADC multiplexing. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what the manufacturer's datasheet alone provides.

AD9237BCPZ-65

AD9237BCPZ-65 - 12-Bit, 65 MSPS, 3V Low-Power ADC | Analog Devices

The Analog Devices AD9237BCPZ-65 is a 12-bit, 65 MSPS, single 3 V supply, low-power analog-to-digital converter (ADC) housed in a 32-pin LFCSP-WQ (5 mm x 5 mm) package with exposed thermal pad. The part integrates a high-performance sample-and-hold amplifier (SHA), an internal voltage reference, and a pipelined core that delivers 65 MSPS conversion rate while drawing approximately 200 mW (typical) from AVDD = 3 V. Differential analog inputs support 2 V p-p full-scale swing; output data is presented as TTL/CMOS-compatible words on a single 12-bit parallel bus. The differential input architecture preserves SFDR and SNR in IF and baseband undersampling systems, making the part well-suited to communications, ultrasound, and instrumentation front ends. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts a continuous-time, continuous-amplitude analog waveform into a discrete-time, discrete-amplitude digital word. In the product taxonomy, the AD9237BCPZ-65 sits under ADC > data converter > mixed-signal IC > semiconductor. Pipeline ADCs such as this use a cascaded switched-capacitor architecture with a back-end digital correction block to reach sample rates from tens to hundreds of MSPS while dissipating far less power than full-flash converters - the converter IC is therefore a power-management-adjacent subsystem that sits between analog signal-conditioning circuitry and an FPGA, DSP, or dedicated clock-and-timing block in the broader signal chain. Key specifications include 12-bit resolution, 65 MSPS maximum sample rate, 69 dB SNR (typical at 65 MSPS with 2 V p-p input), 80 dBc SFDR, an internal 1.0 V reference (with optional external reference drive), and a 3 V analog supply (AVDD) plus a 2.5 V driver supply (DRVDD). The 32-pin LFCSP-WQ exposes the analog inputs, clock input, data outputs, and reference pins, while an exposed die paddle provides a low-theta thermal path required for sustained full-rate operation without derating. Pipeline architecture with 5-bit-per-stage residue gain supports 65 MSPS throughput while keeping per-sample latency low; the digital output stage is synchronized to the rising or falling input clock edge and can drive a 2.5 V CMOS bus into an FPGA capture stage. The proprietary SHA maintains > 250 MHz input bandwidth, enabling IF undersampling of carriers up to about 100 MHz. Typical applications include medical ultrasound imaging receivers, communications IF sampling (GSM/EDGE/UMTS baseband), portable instrumentation and data acquisition, and digital oscilloscope front ends. Its wide input bandwidth also supports CCD/CIS imaging and consumer video digitizers in the 20-65 MSPS class. Designers should follow the recommended layout pattern of separating AVDD/DRVDD planes and routing differential analog inputs as a 100 ohm matched pair into the ADC. The exposed paddle must be soldered to a low-impedance ground pour to keep junction rise below the 125 C operating limit; failure to do this is the most common cause of field failures in 65 MSPS pipeline ADCs.

AD9237BCPZRL7-20

AD9237BCPZRL7-20 - 12-Bit 20 MSPS 3V Low Power ADC | Analog Devices

The Analog Devices AD9237BCPZRL7-20 is a 12-bit, 20 MSPS, monolithic pipelined analog-to-digital converter (ADC) that operates from a single 3 V analog supply and a 2.5 V digital driver supply, housed in a 32-lead LFCSP-WQ (5 mm x 5 mm) package. The -20 speed grade delivers 20 MSPS conversion with 66 dBc SNR to Nyquist at 65 MSPS family maximum, ±0.7 LSB DNL, and 80 dBc SFDR to Nyquist at 65 MSPS, optimizing for ultra-low power consumption in compact multi-channel systems. An ADC is a data converter that transforms continuous analog input signals into discrete digital codes for downstream processing by DSPs, FPGAs, or microcontrollers. The AD9237 family sits at the interface between the analog front-end (amplifiers, filters, sensors) and the digital signal-processing chain, and belongs to the broader category of Nyquist-rate, switched-capacitor, pipeline ADCs. The pipeline architecture uses multiple low-resolution flash stages with inter-stage residue gain and digital error correction, achieving both high sample rate and low latency while consuming milliwatts of power. Key features include a differential analog input stage with selectable input spans from 1 V p-p to 4 V p-p, an on-chip high-performance sample-and-hold amplifier (SHA), an internal 1.0 V voltage reference, and a CMOS-compatible output stage with an Output Enable pin for bus multiplexing. The ADC consumes only 65 mW typical at 20 MSPS with AVDD = 3 V, making it one of the lowest-power 12-bit ADCs of its speed class. The pin-compatible AD9235 (12-bit, 20/40/65 MSPS) further simplifies system migration paths and reduces design complexity across product generations. The AD9237 uses a differential switched-capacitor pipeline core with proprietary SHA architecture that minimizes distortion at the front-end and supports a wide common-mode input range, allowing direct DC-coupling from differential drivers such as the AD8138 or AD8352. The on-chip bandgap reference and reference buffer maintain low temperature drift, and the Output Enable pin allows multiple ADCs to share a digital bus, simplifying board routing in multi-channel systems. Typical applications include portable and battery-powered imaging systems, medical ultrasound front-ends, low-cost I/Q baseband digitizers, hand-held oscilloscope input channels, and industrial inspection cameras. The wide input range scaling also makes it suitable for IF sampling in software-defined radio receivers. When designing with the AD9237BCPZRL7-20, ensure the analog and digital grounds are star-connected to the exposed pad thermal/epitaxy paddle, which must be soldered to a low-impedance ground plane for electrical performance and thermal dissipation. Use a differential input drive topology with a balun or fully differential amplifier for optimum SFDR, and decouple AVDD and DRVDD with 0.1 uF and 10 uF ceramic capacitors placed within a few millimeters of each supply pin.

The AD9237 family is offered in 20 MSPS, 40 MSPS, and 65 MSPS speed grades; this -65 variant is the top-speed member. According to the Analog Devices datasheet, the part is pin-compatible with the AD9235 (a 12-bit 20/40/65 MSPS ADC) enabling drop-in upgrades, and delivers 66 dBc SNR and 80 dBc SFDR to Nyquist at 65 MSPS with ±0.7 LSB DNL. What is a pipelined ADC? A pipelined analog-to-digital converter is a high-speed, multi-stage switched-capacitor architecture that resolves a few bits per stage and combines them with a digital correction stage. Compared to successive-approximation register (SAR) and flash ADCs, pipelined ADCs dominate the 10-250 MSPS range because they deliver the highest sampling rate at moderate resolution (8-14 bits) while keeping die size, power, and cost low. As a member of this category, the AD9237BCPZRL7-65 sits in the broader hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Key features include a flexible analog input range from 1 V p-p to 4 V p-p (differential inputs with adjustable common-mode), an output enable pin for bus multiplexing, internal voltage reference, and ultralow power dissipation scaled to speed grade (lowest at 20 MSPS, highest at 65 MSPS). The single 3 V supply and small 5x5 mm LFCSP footprint make it suited for portable and densely populated boards. Typical applications include communications IF sampling, ultrasound imaging receive channels, portable instrumentation, and low-cost medical imaging front-ends. The output enable pin is useful when multiple ADCs share a digital bus for interleaved or multiplexed data capture. Design tip: the analog inputs are differential - drive them with a low-impedance differential amplifier (such as an AD8138 or ADA4937) for best SFDR, and keep the input common-mode voltage at AVDD/2 to maximize input swing. Decouple AVDD and DRVDD separately with 0.1 uF and 10 uF capacitors placed within 5 mm of the supply pins.

It delivers 70 dBc SNR (to Nyquist) and 85 dBc SFDR, operates from a single 3 V supply (2.7 V to 3.6 V), and features dual high-performance sample-and-hold amplifiers (SHAs) with a 500 MHz differential input bandwidth. Power consumption is approximately 330 mW at 40 MSPS across both channels. An ADC (analog-to-digital converter) is an integrated circuit that samples continuous analog signals and converts them into discrete digital codes for processing by FPGAs, DSPs, or microcontrollers. The AD9238 belongs to the pipelined ADC architecture family - sub-flash converters that achieve high sample rates (tens to hundreds of MSPS) at moderate resolution (10-14 bits) by cascading low-resolution stages with digital error correction. Pipelined ADCs sit between successive-approximation (SAR) and flash converters in the speed/resolution hierarchy and dominate communications, imaging, and instrumentation markets. The -40 speed grade offers 40 MSPS sampling per channel (80 MSPS aggregate for interleaved applications), enabling baseband I/Q capture, ultrasound beamforming, and high-speed test instrumentation. Differential inputs with 500 MHz bandwidth tolerate wideband IF sampling for software-defined radio. The integrated 1.0 V reference eliminates an external component, and the on-chip SHAs front-end relaxes the requirement for external op-amp drivers. The device supports CMOS-compatible output levels on dedicated output drivers, simplifying interface to 3.3 V logic. Typical applications include medical ultrasound imaging, communications basestation receivers, low-cost digital oscilloscopes, and IF sampling for software-defined radio. In ultrasound, the dual-channel matched design supports direct-quadrature demodulation; in communications, the high spurious-free dynamic range enables multicarrier receiver architectures. When designing with the AD9238BSTRL-40, drive the analog inputs in a fully differential configuration to maximize SFDR performance. Use a low-jitter clock source (<1 ps RMS) to preserve aperture-jitter-limited SNR at high input frequencies. Decouple AVDD and DRVDD planes close to the package with separate ferrite beads. For best ENOB at the full 40 MSPS rate, operate the device with an input near -0.5 dBFS to leverage the available headroom.

Key specifications include a 70 dB SNR at 9.7 MHz input (per the AD9238 datasheet), 2 V p-p differential input range, and programmable on-chip input bias modes for AC-coupled or DC-coupled signal chains. The device offers flexible digital output formatting - straight binary, twos complement, and gray code - with LVDS-compatible or CMOS output options. A built-in duty-cycle stabilizer (DCS) compensates for clock duty-cycle distortion, preserving SNR across realistic clock sources. The AD9238 uses a multi-stage pipelined architecture with digital error correction. Each stage quantizes a coarse residue, amplified and passed to the next stage, enabling high throughput with moderate hardware cost. The integrated reference and sample-and-hold amplifiers allow compact PCB designs, especially in multi-channel systems where two matched converters share a common clock and reference. Typical applications include IF signal digitization in communications receivers, multi-channel data acquisition, medical ultrasound beamformers, and portable instrumentation. It is also widely used in radar processing and I/Q demodulation paths in software-defined radio.

AD9240AS

AD9240AS - 14-Bit 10 MSPS ADC | Analog Devices

The Analog Devices AD9240AS is a monolithic 14-bit, 10 MSPS analog-to-digital converter operating from a single +5 V supply and packaged in a 44-pin MQFP. It combines an on-chip sample-and-hold amplifier, a programmable voltage reference, and a flexible analog input structure. The converter supports single-ended or differential input interfaces, making it adaptable to imaging, communications, medical, and data-acquisition systems. An ADC is an analog-to-digital converter, a semiconductor that samples an analog voltage and represents it as a numeric code. The AD9240 belongs to the data-converter hierarchy and uses a pipelined conversion architecture. Its 14-bit resolution supports 16,384 digital codes, while its 10 MSPS rating supports acquisition of up to 10 million samples per second. The reported power dissipation is 285 mW. Key features include 2.5 LSB integral nonlinearity, 0.6 LSB differential nonlinearity, and 0.36 LSB input-referred noise. The differential input structure accepts varying input spans and permits single-ended operation as well as differential operation. The on-chip sample-and-hold amplifier is suitable for multiplexed systems that switch full-scale voltage levels between successive samples, reducing the need for external acquisition circuitry. The AD9240's architecture is designed for low-cost, high-speed data acquisition while maintaining the resolution expected from hybrid converters. Its parallel 14-bit output supports direct connection to digital logic, FPGA fabric, DSP input latches, or data-capture hardware when timing and bus-width requirements are carefully matched. The programmable reference can be supplemented by an external reference when dc accuracy or temperature drift requirements exceed the internal-reference requirements. Typical applications include medical imaging, communications receivers, industrial data acquisition, imaging systems, and instrumentation. The differential input path can improve common-mode rejection when the source is balanced, while single-ended input simplifies lower-cost front ends. System designers should verify signal amplitude, reference voltage, clock jitter, output timing, and package-level thermal performance against the manufacturer datasheet.

AD9280ARSRL - 8-Bit 32 MSPS CMOS ADC | Analog Devices

The Analog Devices AD9280ARSRL is a monolithic, single-supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference, housed in a 28-pin SSOP package supplied on tape and reel. The converter operates from a single +2.7 V to +5.5 V supply, dissipating only 95 mW at 3 V supply while delivering 32 MSPS throughput with no missing codes guaranteed over the full operating temperature range. What is a pipelined CMOS ADC? A pipelined analog-to-digital converter is a high-speed data converter architecture that processes the analog input through multiple low-resolution stage ADCs in series, with each stage handling a portion of the conversion before passing a residue to the next stage. Pipelined ADCs sit within the broader hierarchy of ADC -> data converter -> mixed-signal IC -> semiconductor, and are the dominant architecture for sampling rates between roughly 10 MSPS and several hundred MSPS where successive-approximation (SAR) converters become too slow and flash converters become impractical. The on-chip sample-and-hold (SHA) front-end and integrated voltage reference are critical to eliminating external component count and simplifying PCB layout at high frequencies. Key features of the AD9280ARSRL include a pin-compatible upgrade path from the legacy AD876-8, differential nonlinearity (DNL) of 0.2 LSB, a power-down (sleep) mode for battery-powered applications, three-state outputs for bus sharing, and an out-of-range indicator that flags overranged input conditions. The 300 MHz onboard sample-and-hold amplifier can be configured for either single-ended or differential inputs, providing flexibility for direct-IF sampling or baseband signal acquisition. The AD9280 uses a multistage differential pipeline architecture, which provides inherent latency of several clock cycles but enables the 32 MSPS conversion rate without the power penalty of flash architectures. Internal registers and the proprietary reference design eliminate the need for external reference components, while the integrated SHA relaxes the input driver bandwidth requirement. Typical applications include video digitizers, CCD/camera imaging front-ends, digital oscilloscope front-ends, IF sampling in communication receivers, medical imaging, and low-cost consumer digital still cameras. The wide supply range supports both 3 V portable designs and 5 V industrial platforms. When designing with this ADC, ensure the analog input is driven by a low-impedance, bandwidth-appropriate buffer; the SHA 3 dB corner frequency must be considered when using the high-pass-coupling configuration. The three-state output mode requires careful bus-arbiter logic to prevent contention when multiple converters share a data bus.

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.

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.
