The ADS1602 is a high performance analog-to-digital converter with high sampling rate, low power consumption and outstanding anti-noise performance. The product is suitable for various applications such as sonar, vibration analysis and data acquisition.
The ADS1602 is a high‑speed, high‑precision 16‑bit delta‑sigma analog‑to‑digital converter offering a 2.5 MSPS data rate and a 1.23 MHz bandwidth. It features a simple 3‑wire serial interface, on‑chip digital filtering, low power consumption (530 mW at full speed), and a selectable on‑chip voltage reference.
The datasheet provides absolute maximum ratings, detailed electrical characteristics, pin assignments, timing diagrams, mechanical dimensions for the 7 mm × 7 mm TQFP‑48 package, and definitions of key parameters such as SNR, THD, SFDR, and power‑down mode.
