SNAS281G –FEBRUARY 2005–REVISED MARCH 2013

ADC102S021 2 Channel, 50 ksps to 200 ksps, 10-Bit A/D Converter

Check for Samples: ADC102S021

FEATURES

DESCRIPTION

The ADC102S021 is

a low-power, two-channel

•

Specified Over a Range of Sample Rates.

Two Input Channels

CMOS 10-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 ADC102S021 is fully specified over a

sample rate range of 50 ksps to 200 ksps. The

converter is based on a successive-approximation

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

signals at inputs IN1 and IN2.

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: ± 0.13 LSB (typ)

INL: ± 0.13 LSB (typ)

SNR: 61.8 dB (typ)

Power Consumption

The ADC102S021 operates with a single supply that

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

consumption using a +3V or +5V supply is 1.94 mW

and 6.9 mW, respectively. The power-down feature

reduces the power consumption to just 0.12 µW using

a +3V supply, or 0.47 µW using a +5V supply.

–

3V Supply: 1.94mW (typ)

5V Supply: 6.9 mW (typ)

The ADC102S021 is packaged in an 8-lead VSSOP

package. Operation is specified over the industrial

temperature range of −40°C to +85°C.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
