12-bit 1-MHz SAR ADC

Description

Features

 16 or 8-channel 12-Bit SAR ADC

The TPC5120/TPC5121 products include capacitor-

based SAR A/D converters with inherent sample and

hold. The TPC5120 has 16-channel single-ended

inputs and the TPC5121 has 8-channel single-ended

inputs.

− Supporting Ranges from 0 to 2.5 V and 0 to 5

− Programmable Out-of-Range Alarms

− 1-MHz Sample Rate Serial Devices

 General Purpose I/O Ports (GPIOs)

 Low-Power SPI-Compatible Serial Interface

 Operating Temperature: −40°C to 125°C

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

Applications

 Wireless Infrastructure

 PLC / DCS

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 × VREF), individually

configurable GPIOs (four in case of the TSSOP and

one on the VQFN package devices), 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.
