Overview
AD9608BCPZ-125 from Analog Devices is a dual-channel, 10-bit, 125 MSPS analog-to-digital converter operating from a single 1.8 V analog supply, featuring differential 650 MHz analog input bandwidth, 61.7 dBFS SNR at 70 MHz, and on-chip voltage reference and sample-and-hold circuitry-used in I/Q demodulation systems and ultrasound front-ends.
For engineers reviewing the AD9608BCPZ-125 datasheet, AD9608BCPZ-125 pinout, AD9608BCPZ-125 application, or AD9608BCPZ-125 equivalent, this page delivers verified specifications, CMOS/LVDS output configuration options, dual-channel timing alignment details, industrial temperature range (−40°C to +85°C) operation, and LFCSP-64 package implementation guidance.
Technical Context
The AD9608BCPZ-125 employs a multistage differential pipeline architecture with output error correction logic to guarantee 10-bit accuracy and no missing codes across temperature. It supports IF sampling up to 200 MHz using a patented sample-and-hold circuit optimized for low power and wide input bandwidth.
Its digital interface includes programmable clock/data alignment, integer 1-to-8 input clock divider, and selectable data output formats (offset binary, Gray code, twos complement). The device provides independent DCO outputs per channel and supports both CMOS and LVDS logic families via separate DRVDD supply.

FAQ
What is the maximum analog input frequency supported by the AD9608BCPZ-125?
The AD9608BCPZ-125 supports IF sampling frequencies up to 200 MHz with its 650 MHz analog input bandwidth. This is enabled by its patented sample-and-hold circuit, which maintains 61.7 dBFS SNR even at 200 MHz input-making the AD9608BCPZ-125 suitable for direct RF sampling in broadband receivers and ultrasound front-ends.
Does the AD9608BCPZ-125 support both CMOS and LVDS output interfaces?
Yes, the AD9608BCPZ-125 supports both 1.8 V CMOS and 1.8 V LVDS digital outputs via its dedicated DRVDD supply rail. Output mode is selected through SPI configuration or hardware pins, and each channel has its own DCO for source-synchronous timing-ensuring reliable data capture in either interface, as specified in the AD9608BCPZ-125 datasheet Rev. C.
What is the power consumption of the AD9608BCPZ-125 at 125 MSPS?
At 125 MSPS with 1.8 V CMOS outputs, the AD9608BCPZ-125 consumes 199 mW total (95 mW per channel). In LVDS mode, total power rises to 247 mW due to higher driver current. Standby power is 108–120 mW, and power-down mode reduces consumption to just 2.0 mW-critical for battery-operated devices using the AD9608BCPZ-125.
Is the AD9608BCPZ-125 pin-compatible with other Analog Devices ADCs?
Yes, the AD9608BCPZ-125 uses a 64-lead LFCSP package pin-compatible with the AD9650, AD9269, AD9268, AD9258, AD9648, AD9628, AD9231, and AD9204 families. This enables straightforward migration between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS-without PCB redesign when upgrading resolution or speed using the AD9608BCPZ-125.
What clocking features does the AD9608BCPZ-125 provide to simplify system synchronization?
The AD9608BCPZ-125 includes an optional duty cycle stabilizer (DCS), integer 1-to-8 input clock divider, and programmable DCO/data alignment. These features reduce external clock conditioning requirements, enable flexible master clock distribution, and ensure deterministic inter-channel timing-key for coherent sampling in diversity radio and ultrasound beamforming systems using the AD9608BCPZ-125.
