ADC124S051

4 Channel, 500 kSPS, 12-Bit A/D Converter

General Description

Features

n Specified over a range of sample rates.

n Four input channels

The ADC124S051 is a low-power, four-channel CMOS 12-bit

analog-to-digital converter with a high-speed serial interface.

Unlike the conventional practice of specifying performance

at a single sample rate only, the ADC124S051 is fully speci-

fied over a sample rate range of 200 kSPS to 500 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 four input signals at inputs IN1

through IN4.

n Variable power management

n Single power supply with 2.7V - 5.25V range

Key Specifications

n DNL

n INL

+0.7 / −0.4 LSB (typ)

0.5 LSB (typ)

n SNR

72.5 dB (typ)

The output serial data is straight binary, and is compatible

n Power Consumption

— 3V Supply

— 5V Supply

™

with several standards, such as SPI , QSPI , MICROW-

IRE and many common DSP serial interfaces.

3.0 mW (typ)

10.0 mW (typ)

The ADC124S051 operates with a single supply that can

range from +2.7V to +5.25V. Normal power consumption

using a +3V or +5V supply is 3.0 mW and 10.0 mW, respec-

tively. The power-down feature reduces the power consump-

tion to just 0.14 µW using a +3V supply, or 0.32 µW using a

+5V supply.

Applications

n Portable Systems

n Remote Data Aquisitions

n Instrumentation and Control Systems

The ADC124S051 is packaged in a 10-lead MSOP package.

Operation over the industrial temperature range of −40˚C to

+85˚C is guaranteed.

Pin-Compatible Alternatives by Resolution and Speed

All devices are fully pin and function compatible.
