AD7760BSVZ-REEL

Overview

The AD7760BSVZ-REEL is a high-performance, 24-bit Sigma-Delta analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum fully filtered output word rate of 2.5 MHz and achieves a Signal-to-Noise Ratio (SNR) of 100 dB at this speed. The device features a dynamic range of 120 dB at a 78 kHz output data rate and includes an on-chip differential amplifier for signal buffering. It utilizes a parallel interface and is housed in a 64-lead TQFP package with an exposed paddle. The component is specified over the industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a low-pass finite impulse response (FIR) digital filter with default or user-programmable coefficients.
• Includes an on-chip differential amplifier designed for signal buffering and level shifting.
• Provides programmable oversampling rates ranging from 8x to 256x.
• Features internal digital offset and gain correction registers for calibration.

Applications

• Data acquisition systems
• Vibration analysis
• Instrumentation

Procurement Notes

Verify that the ordering suffix REEL corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm the specific revision A datasheet aligns with the manufacturing date code to ensure parameter consistency. Check RoHS compliance documentation for environmental regulatory adherence in the target market.

Selection Notes

Select this component when high-speed data acquisition requires a wide input bandwidth combined with high resolution. The integrated buffer reduces external signal conditioning complexity. Ensure the system design accommodates the multiple power supply rails and decoupling requirements specified in the datasheet for optimal noise performance.

Part Context

This part belongs to the AD7760 series of Sigma-Delta ADCs. Related devices include the AD7762 and AD7763, which offer similar 24-bit resolution but operate at lower speeds of 625 kSPS. The AD7760 is distinguished by its higher 2.5 MSPS throughput capability while maintaining comparable dynamic range specifications.

Replacement Considerations

The AD7762BSVZ-REEL offers a compatible alternative with a 625 kSPS maximum output rate. Verify that the reduced speed meets application timing requirements before substitution.
