The ADS9324 is a 16-channel, integrated data acquisition (DAQ) system based on a simultaneous-sampling, 16-bit successive approximation (SAR) analog-to-digital converter (ADC) operating at a maximum of 1MSPS per channel. The device features a complete analog front-end for each channel, including a programmable gain amplifier (PGA) with input impedance of 1MΩ, input clamp, low-pass filter, and an ADC input driver. The device also features a low-drift, precision reference with a buffer to drive the ADC. The high input impedance allows direct connection with sensors and transformers, thus eliminating the need for external driver circuits. The device supports both differential and single-ended inputs, allowing it to be used with various sensor outputs.
The ADS9324 includes a flexible digital interface allowing it to be used with a variety of host controllers. Users can configure the serial interface to read the ADC output on 1-lane, 2-lane, 4-lane, and 8-lane. The device also has flexibility to operate the ADC as 2-CH, 4-CH, 8-CH and 16-CH simultaneous sampling ADC.
