AD9238BSTRL-65

Overview

The AD9238BSTRL-65 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 65 MSPS with a single 3 V supply. The device features differential inputs with a 500 MHz bandwidth and an integrated voltage reference. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70 dB and Spurious-Free Dynamic Range (SFDR) of 80.5 dBc at full scale. Power consumption is 640 mW at maximum speed. It utilizes a pipelined architecture with output error correction logic to guarantee no missing codes across the industrial temperature range.

Feature Summary

• Dual high-performance sample-and-hold amplifiers (SHAs) with differential input capability
• Integrated duty cycle stabilizer for maintaining performance under clock variations
• Flexible analog input range supporting 1 V p-p to 2 V p-p signals
• Multiplexed data output option enabling single-port operation

Applications

• Ultrasound equipment
• Direct conversion or IF sampling receivers
• WB-CDMA, CDMA2000, WiMAX systems
• Battery-powered instruments
• Low cost digital oscilloscopes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range and power supply voltages before finalizing procurement orders.

Selection Notes

Select this component when dual-channel synchronization and high dynamic range are required in a compact form factor. Consider the 65 MSPS speed grade if system latency and power budget allow for higher dissipation compared to lower-speed variants.

Part Context

This part belongs to the AD9238 family of dual 12-bit ADCs. It is pin-compatible with the AD9248 14-bit variant, allowing for design flexibility. The device is fabricated on an advanced CMOS process and is available in 64-lead LQFP or LFCSP packages.

Replacement Considerations

The AD9238BSTZRL-65 is functionally equivalent to the AD9238BSTZ-65, differing primarily in packaging format (Tape & Reel vs. Tube). Verify pinout compatibility if substituting between package types.
