16-Bit Synchronous Sampling ADC GX7612 Replaces AD7612 for Automatic Test Equipment (ATE)

Automatic Test Equipment (ATE) is an automated system used for functional, performance, and reliability testing of electronic devices. Through programmable test sequences, the system precisely controls stimulus signal generation and efficiently analyzes acquired data. Among ATE‘s critical components, the high-precision conversion and flexible input range of analog-to-digital converters ensure product quality and reliability.

GXSC‘s single-channel 16-bit 750kSPS synchronous sampling ADC GX7612 is ideally suited for ATE applications. The GX7612 is compatible with the imported AD7612. Powered by a single 5V supply, it features a programmable input range supporting true bipolar signals with options including 5V, 10V, ±5V, and ±10V. Its built-in correction algorithms comprehensively enhance dynamic and static performance, delivering bipolar zero-level error as low as ±2 LSB and linearity below 1 LSB. Operating on a single 5V supply, it achieves lower power consumption.

The GX7612 incorporates an input buffer with 1MΩ input impedance and an anti-aliasing filter for direct analog signal acquisition. It also integrates a configurable high-precision reference voltage generator and buffer, simplifying PCB design for data acquisition systems through high integration. The GX7612 supports parallel or serial modes, configurable via different hardware pin connections. This capability creates multiple connection options for interfacing the device with microprocessors or DSPs.
