The ADS8345 is a 16-bit, 8-channel, sampling Analog-to-Digital (A/D) converter with a synchronous serial interface. The device features a single supply of 2.7V to 5V, up to 100kHz conversion rate, 8 single-ended or 4 differential input, and 85dB SINAD. The ADS8345 is ideal for battery-operated systems such as personal digital assistants, portable multi-channel data log- gers, and measurement equipment.
The ADS8345 is an 8‑channel, 16‑bit A/D converter with a synchronous serial interface. It operates from a single supply of 2.7 V to 5 V and provides bipolar input range, low power consumption (typical 8 mW at 100 kHz), and a shutdown mode for ultra‑low power.
The device is offered in QSOP‑20 and SSOP‑20 packages and is specified for temperatures from –40 °C to +85 °C. It is suited for data‑acquisition, test equipment, industrial process control, PDAs, and battery‑powered systems.
