TPC5120Q

12-Bit 16-Channel 1-MSPS SAR ADC

Overview

The TPC5120Q includes a capacitor-based SAR A/D converter with inherent sample and hold. TPC5120Q has 16 channel single-ended inputs.

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

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

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 software selectable input ranges (0 V to VREF and 0 V to 2 x VREF), individually configurable GPIOs, 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.
