12-Bit, 1 MSPS, Single-Supply, Two-Chip Data Acquisition System for Piezoelectric Sensors (CN0350)

The circuit shown in Figure 1 is a 12-bit, 1 MSPS data acquisition system utilizing only two active devices.The system processes charge input signals from piezoelectric sensors using a single 3.3 V supply and has a total error of less than 0.25% FSR after calibration over a ±10°C temperature range, making it ideal for a wide variety of laboratory and industrial measurements.


The small footprint of the circuit makes this combination an industry-leading solution for data acquisition systems where accuracy, speed, cost, and size play a critical role.
