AD7760BSVZ

Overview

The AD7760BSVZ is a high-performance, 24-bit Sigma-Delta analog-to-digital converter (ADC) from Analog Devices Inc. It features a fully differential modulator input and an on-chip differential amplifier for signal buffering. The device supports a maximum output data rate of 2.5 MSPS with a Signal-to-Noise Ratio (SNR) of 100 dB at this speed, or 112 dB at 78 kHz. It includes a low-pass finite impulse response (FIR) filter with programmable coefficients and digital offset/gain correction registers. The component operates within an industrial temperature range of -40°C to +85°C and utilizes a parallel interface.

Feature Summary

• Integrates a fully differential Sigma-Delta modulator with an on-chip differential amplifier for signal buffering and level shifting.
• Features a low-pass finite impulse response (FIR) digital filter with default or user-programmable coefficients for noise shaping.
• Includes internal digital offset and gain correction registers to enhance DC accuracy without external calibration components.
• Supports synchronization of multiple devices via a dedicated SYNC pin for system-level timing alignment.

Applications

• Data acquisition systems
• Vibration analysis
• Instrumentation

Procurement Notes

Verify the specific suffix 'BSVZ' against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure the required power supply voltages (AVDD1/AVDD2/DVDD) match the design specifications before procurement. Confirm that the parallel interface requirements align with the host controller capabilities.

Selection Notes

Select this component when high-speed data acquisition requires wide dynamic range and minimal external antialiasing filtering. Consider the on-chip buffer if the application demands simplified front-end signal conditioning. Evaluate the power dissipation in normal versus low-power modes based on thermal constraints and performance requirements.

Part Context

The AD7760 belongs to the AD7760 series of Sigma-Delta ADCs. Related devices include the AD7762, which offers 625 kSPS performance, and the AD7763, which provides serial interface connectivity. These variants share similar architectural benefits but differ in speed and interface protocols to suit different system integration needs.
