ADC128S022

8-Channel, 50 kSPS to 200 kSPS, 12-Bit A/D Converter

General Description

Features

n Eight input channels

The ADC128S022 is a low-power, eight-channel CMOS 12-

bit analog-to-digital converter specified for conversion

throughput rates of 50 kSPS to 200 kSPS. The converter is

based on a successive-approximation register architecture

with an internal track-and-hold circuit. It can be configured to

accept up to eight input signals at inputs IN0 through IN7.

n Variable power management

n Independent analog and digital supplies

™

n SPI /QSPI /MICROWIRE /DSP compatible

n Packaged in 16-lead TSSOP

The output serial data is straight binary and is compatible

Key Specifications

and many common DSP serial interfaces.

The ADC128S022 may be operated with independent ana-

log and digital supplies. The analog supply (V_A) can range

from +2.7V to +5.25V, and the digital supply (V_D) can range

from +2.7V to V_A. Normal power consumption using a +3V or

+5V supply is 1.2 mW and 7.5 mW, respectively. The power-

down feature reduces the power consumption to 0.06 µW

using a +3V supply and 0.25 µW using a +5V supply.

The ADC128S022 is packaged in a 16-lead TSSOP pack-

age. Operation over the extended industrial temperature

range of −40˚C to +105˚C is guaranteed.
