Product details
Overview
AD9287BCPZ-100 from Analog Devices is a quad-channel, 8-bit, 100 MSPS analog-to-digital converter with serial LVDS output, 1.8 V supply operation, 295 MHz full-power analog bandwidth, and on-chip sample-and-hold-designed for portable ultrasound beam-forming and quadrature radio receivers.
For engineers reviewing the AD9287BCPZ-100 datasheet, AD9287BCPZ-100 pinout, AD9287BCPZ-100 application, or AD9287BCPZ-100 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial temperature range (−40°C to +85°C), RoHS-compliant 48-lead LFCSP package mapping, and real-world timing and linearity performance data.
Technical Context
The AD9287BCPZ-100 implements a 3-section pipelined ADC architecture: a 4-bit first stage, eight 1.5-bit interstage sections with MDAC-based residue amplification, and a final 3-bit flash stage-enabling 8-bit resolution at 100 MSPS with 8 clock-cycle pipeline latency. Each stage includes 1-bit redundancy for digital error correction.
It supports dual LVDS output modes: ANSI-644–compliant serial LVDS (247–454 mV differential output voltage) and low-power reduced-signal LVDS (150–250 mV), both with offset binary coding. Clock alignment, data framing, and bit orientation are programmable via SPI interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Supply Voltage | 1.8 V AVDD/DRVDD - simplifies power delivery with single low-voltage rail and eliminates need for level-shifting interfaces. |
Pinout & Package
The AD9287BCPZ-100 is housed in a RoHS-compliant, 48-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle requiring connection to analog ground (AGND). Package dimensions: 7 mm × 7 mm × 0.85 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVDD (Pins 1,2,5,9,10,27,32,35,36,39,45,46) | Analog supply input | 1.8 V power for ADC core; multiple pins reduce IR drop and improve PSRR. |
| VIN+ A / VIN− A (Pins 33,34) | Differential analog input channel A | Accepts 2 V p-p differential signal; 7 pF input capacitance requires matched layout for optimal bandwidth. |
| D+ A / D− A (Pins 19,20) | LVDS serial data output channel A | ANSI-644–compliant outputs; configurable for standard or low-power LVDS mode via SPI. |
| CLK+ / CLK− (Pins 29,30) | Differential sampling clock input | Accepts CMOS/LVDS/LVPECL; 250 mV p-p minimum swing ensures reliable latching at 100 MSPS. |
| DCO+ / DCO− (Pins 23,24) | Data clock output | DDR-capable clock synchronized to serialized data; used by FPGA/ASIC to capture LVDS stream. |
| FCO+ / FCO− (Pins 21,22) | Frame clock output | Indicates start of new 8-bit byte; critical for byte alignment in multi-channel time-interleaved systems. |
| PDWN (Pin 6) | Global power-down control | Active-low; reduces total dissipation to <4 mW when asserted-ideal for duty-cycled acquisition. |
| SCLK/DTP, SDIO/ODM, CSB (Pins 8,9,30) | SPI serial port interface | Configures clock/data alignment, test patterns, output resolution, and standby mode. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent 8-bit ADCs in one 7 mm × 7 mm LFCSP-reduces PCB area and inter-channel skew vs. discrete solutions. |
| Programmable clock/data alignment | SPI-adjustable delay between DCO and data edges (±300 ps range)-enables timing closure on high-speed FPGA interfaces. |
| Built-in digital test pattern generation | Supports deterministic, pseudorandom, and custom user-defined patterns-accelerates board-level validation without external signal sources. |
| Individual-channel power-down | Each ADC can be disabled independently; residual dissipation <2 mW per channel-optimizes power in partial-acquisition modes. |
| Flexible bit orientation | Configurable MSB-first or LSB-first serialization-matches native word ordering of downstream processors or DSPs. |
| Standby mode | 72 mW quiescent power with fast 600 ns wake-up-preserves system responsiveness during idle intervals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9219BCPZ-105 | 10-bit resolution, 105 MSPS, same 48-lead LFCSP package and pinout | Higher ENOB (8.7 bits) and SFDR (75 dBc) but higher power (220 mW/channel) | Select when >8-bit resolution is required for improved dynamic range in spectral analysis or radar pulse detection. |
| AD9228BCPZ-50 | 12-bit resolution, 50 MSPS, same LFCSP footprint and SPI interface | Lower sampling rate but superior SNR (70 dB) and INL (±0.5 LSB); not pin-compatible | Select for high-precision, lower-bandwidth applications like vibration monitoring or precision instrumentation where speed is secondary to accuracy. |
Compared with AD9287BCPZ-100, the AD9219BCPZ-105 offers higher resolution at marginally increased speed and power, while the AD9228BCPZ-50 trades speed for significantly enhanced DC accuracy and noise floor-making each suitable for distinct trade-off priorities in multi-channel acquisition systems.

FAQ
What is the maximum analog input frequency supported by the AD9287BCPZ-100?
The AD9287BCPZ-100 has a full-power analog bandwidth of 295 MHz, meaning it maintains specified dynamic performance (SNR, SFDR) for input signals up to that frequency. This enables direct sampling of wideband IF signals without external anti-alias filtering, and is validated per Figure 34 in the Rev. G datasheet.
Does the AD9287BCPZ-100 support independent power-down of individual ADC channels?
Yes, the AD9287BCPZ-100 supports individual-channel power-down via SPI register control. When all four channels are disabled, total dissipation drops to less than 4 mW. Each channel's power state is configurable separately, enabling flexible power management in burst-mode acquisition systems.
What LVDS output standards does the AD9287BCPZ-100 comply with?
The AD9287BCPZ-100 supports two LVDS output modes: default ANSI-644–compliant serial LVDS (247–454 mV differential voltage) and a low-power reduced-signal option (150–250 mV) compatible with IEEE 1596.3. Both modes use offset binary coding and are selectable via SPI configuration.
Is the AD9287BCPZ-100 pin-compatible with other members of the AD92xx family?
Yes-the AD9287BCPZ-100 shares the same 48-lead LFCSP package and pinout with the AD9219 (10-bit) and AD9228 (12-bit) as noted in the Product Highlights section of the datasheet. This enables hardware reuse across resolution tiers in platform-based designs.
What is the pipeline latency of the AD9287BCPZ-100, and how does it affect system timing?
The AD9287BCPZ-100 has a fixed pipeline latency of 8 clock cycles, measured from the rising edge of the sampling clock to valid data at the LVDS output. This deterministic delay is critical for time-sensitive applications such as closed-loop beam-forming or real-time signal processing, and is explicitly specified in Table 4 of the Rev. G datasheet.
