ADC081S051

Single Channel, 500 kSPS, 8-Bit A/D Converter

General Description

Features

n Specified over a range of sample rates.

n 6-lead LLP package

The ADC081S051 is a low-power, single channel CMOS

8-bit analog-to-digital converter with a high-speed serial in-

terface. Unlike the conventional practice of specifying per-

formance at a single sample rate only, the ADC081S051 is

fully specified over a sample rate range of 200 kSPS to 500

n Variable power management

n Single power supply with 2.7V - 5.25V range

™

n SPI /QSPI /MICROWIRE/DSP compatible

kSPS. The converter is based on

successive-

approximation register architecture with an internal track-

and-hold circuit.

Key Specifications

n DNL

+ 0.07 / −0.06 LSB (typ)

+ 0.06 / −0.07 LSB (typ)

49.6 dB (typ)

The output serial data is straight binary, and is compatible

n INL

n SNR

™

with several standards, such as SPI

QSPI

MICROWIRE, and many common DSP serial interfaces.

n Power Consumption

— 3V Supply

— 5V Supply

The ADC081S051 operates with a single supply that can

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

using a +3V or +5V supply is 2.9 mW and 10.5 mW, respec-

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

tion to as low as 2.6 µW using a +5V supply.

2.9 mW (typ)

10.5 mW (typ)

Applications

n Portable Systems

n Remote Data Aquisitions

The ADC081S051 is packaged in an 6-lead LLP package.

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

+85˚C is guaranteed.

n Instrumentation and Control Systems

Pin-Compatible Alternatives by Resolution and Speed

All devices are fully pin and function compatible.
