Overview
The AD9238BSTZ-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. It utilizes a multistage differential pipelined architecture to ensure no missing codes across the full operating temperature range. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 70.2 dB at 9.7 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 84.0 dBc. Power consumption is rated at 330 mW DC input at the 40 MSPS speed grade.
Feature Summary
- Dual-channel 12-bit ADC with integrated voltage reference
- Multistage differential pipelined architecture ensuring no missing codes
- Clock duty cycle stabilizer for performance maintenance
- Flexible analog input supporting differential or single-ended configurations
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 data sheet to confirm package type and speed grade. Ensure compatibility with system power supplies and clock requirements before integration. Check for RoHS compliance status as indicated in official documentation.
Selection Notes
Select this component for applications requiring dual-channel digitization at moderate speeds. Consider the 40 MSPS speed grade for balanced power and performance. Verify that the 3 V supply voltage aligns with system constraints. Evaluate the need for the integrated reference versus external options based on noise requirements.
Part Context
The AD9238 belongs to a family of dual 12-bit ADCs offering multiple speed grades. It is pin-compatible with the AD9248, which provides 14-bit resolution. The BSTZ suffix indicates a Pb-free LQFP package. This part is designed for industrial temperature ranges and supports flexible input and output configurations.
Replacement Considerations
The AD9238BSTZ-20 and AD9238BSTZ-65 are pin-compatible variants within the same family, differing only in maximum sampling rates. The AD9248 series offers higher resolution but may require different power management considerations.
