SNAS279E –APRIL 2005–REVISED MARCH 2013

ADC084S021 4-Channel, 50 ksps to 200 Ksps, 8-Bit A/D Converter

Check for Samples: ADC084S021

FEATURES

DESCRIPTION

The ADC084S021 is

•

Specified Over a Range of Sample Rates.

Four Input Channels

a low-power, four-channel

CMOS 8-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 ADC084S021 is fully specified over a

sample rate range of 50 ksps to 200 ksps. The

converter is based upon a successive-approximation

circuit. It can be configured to accept up to four input

signals at inputs IN1 through IN4.

Variable Power Management

Single Power Supply with 2.7V - 5.25V Range

APPLICATIONS

•

Portable Systems

Remote Data Acquisition

Instrumentation and Control Systems

The output serial data is straight binary, and is

compatible with several standards, such as SPI™,

QSPI™, MICROWIRE, and many common DSP

serial interfaces.

KEY SPECIFICATIONS

•

DNL: ±0.04 LSB (typ)

INL: ±0.04 LSB (typ)

SNR: 49.6 dB (typ)

Power Consumption

The ADC084S021 operates with a single supply that

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

consumption using a +3V or +5V supply is 1.6 mW

and 5.8 mW, respectively. The power-down feature

reduces the power consumption to just 0.12 µW using

a +3V supply, or 0.35 µW using a +5V supply.

–

3V Supply: 1.6 mW (typ)

5V Supply: 5.8 mW (typ)

The ADC084S021 is packaged in a 10-lead VSSOP

package. Operation over the industrial temperature

range of −40°C to +85°C is ensured.
