概述

The TPC5121 series includes capacitor-based SAR A/D converters with inherent sample and hold. The TPC5121 has 8-channel single-ended inputs.

The devices accept a wide analog supply range from 2.7 V to 5.25 V. The ultra-low power consumption makes these devices suitable for battery-powered and isolated power-supply applications.

A wide 1.7-V to 5.25-V I/O supply range facilitates a glueless interface with the most used digital hosts. The serial interface is controlled by CS and SCLK for easy connection with microprocessors and DSPs.

The input signal is sampled with the falling edge of CS. It uses SCLK for conversion, serial data output, and reading serial data in. The devices allow auto sequencing of preselected channels or manual selection of a channel for the next conversion cycle. There are two softwareselectable input ranges (0 V to V_REF and 0 V to 2 × V_REF), and two programmable alarm thresholds per channel. These features make the devices suitable for most data acquisition applications.

The devices offer an attractive power-down feature. This is extremely useful for power saving when the device is operated at lower conversion speeds.
