AD9640ABCPZRL7-125

Analog To Digital Converters (ADC) Overview

The AD9640ABCPZRL7-125 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 125 MSPS with a differential pipelined architecture. The device features a 650 MHz analog input bandwidth and supports flexible input ranges from 1 V p-p to 2 V p-p. Power consumption is specified at 750 mW at the maximum sampling rate using a single 1.8 V analog supply. Digital outputs are configurable for 1.8 V to 3.3 V CMOS or 1.8 V LVDS operation. It includes an internal voltage reference, clock duty cycle stabilizer, and serial port control interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing components. Confirm that the ABCPZ designation corresponds to the lead-free LFCSP package variant. Ensure compatibility with the required 125 MSPS speed grade before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low power in a compact form factor. Verify that the system clock frequency aligns with the integer divider capabilities up to 625 MHz. Ensure the host logic family matches the selectable DRVDD voltage range for proper signal interfacing.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9640 series, which offers multiple speed grades including 80, 105, 125, and 150 MSPS variants. The AD9640ABCPZRL7-125 specifically denotes the 125 MSPS performance bin within the industrial temperature range family.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include other speed grades within the AD9640 family such as AD9640BCPZ-125 or AD9640ABCPZ-150. Migration to lower resolution devices like the AD9627 or AD9600 is also supported via pin compatibility.
