AD9238BCPZRL-40

Overview

The AD9238BCPZRL-40 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 40 MSPS with a single 3 V supply. The device features dual high-performance sample-and-hold amplifiers and an integrated voltage reference. Key electrical parameters include a typical Signal-to-Noise Ratio (SNR) of 70.4 dB at 25°C for a 2.4 MHz input, and a Spurious-Free Dynamic Range (SFDR) of 86.0 dBc. Power consumption is specified at 330 mW DC input and 397 mW sine wave input. It utilizes a multistage differential pipelined architecture to guarantee no missing codes across the full operating temperature range.

Feature Summary

Dual-channel architecture with independent sample-and-hold amplifiers
Integrated voltage reference with selectable modes
Clock duty cycle stabilizer for performance maintenance
Multiplexed data output option for single-port operation

Applications

Ultrasound equipment
Direct conversion or IF sampling receivers
WB-CDMA, CDMA2000, WiMAX systems
Battery-powered instruments
Hand-held scopemeters

Procurement Notes

Verify the specific speed grade suffix matches the required sampling rate. Confirm the package type corresponds to the design footprint. Check the revision level against the latest datasheet for any specification updates. Ensure environmental ratings align with the target application conditions.

Selection Notes

Select this component when dual-channel acquisition at 40 MSPS is required. Consider the 12-bit resolution and dynamic performance metrics for signal fidelity needs. Evaluate power consumption constraints against the 330 mW typical draw. Verify interface compatibility with the host digital system.

Part Context

This part belongs to the AD9238 family, which includes variants operating at 20 MSPS and 65 MSPS. It shares pin compatibility with the AD9248 14-bit ADC. The BCPZRL designation indicates a 64-lead LFCSP package in a reel format.
