FEATURES

DESCRIPTION

The

interface.

Unlike

the

conventional

practice of specifying performance at a single sample

rate only, the ADC082S101 is fully specified over a

Single Power Supply with 2.7V - 5.25V Range

sample rate range of 500 ksps to 1 Msps. The

converter is based on a successive-approximation

DNL: ±0.10 LSB (typ)

circuit. It can be configured to accept one or two input

signals at inputs IN1 and IN2.

•

INL: ± 0.13 LSB (typ)

•

SNR: 49.6 dB (typ)

The output serial data is straight binary, and is

compatible with several standards, such as SPI™,

–

5V Supply: 11.4 mW (typ)

The ADC082S101 operates with a single supply that

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

and 9.6 mW, respectively. The power-down feature

reduces the power consumption to just 0.12 µW using

Instrumentation and Control Systems

The ADC082S101 is packaged in an 8-lead VSSOP

package. Operation over the industrial temperature

range of

−40°C to +85°C is ensured.
