T he AD7880 is a high speed, low power, 12-bit A/D converter

which operates from a single +5 V supply. It consists of a 3 µs

track/hold amplifier, a 12 µs successive-approximation ADC,

versatile interface logic and a multiple-input-range circuit. T he

part also includes a power save feature.

1. Fast Conversion T ime.

12 µs conversion time and 3 µs acquisition time allow for

large input signal bandwidth. T his performance is ideally

suited for applications in areas such as telecommunications,

audio, sonar and radar signal processing.

An internal resistor network allows the part to accept both uni-

polar and bipolar input signals while operating from a single

+5 V supply. Fast bus access times and standard control inputs

ensure easy interfacing to modern microprocessors and digital

signal processors.

2. Low Power Consumption.

2 mW power consumption in the power-down mode makes

the part ideally suited for portable, hand held, battery pow-

ered applications.

3. Multiple Input Ranges.

T he AD7880 features a total throughput time of 15 µs and can

convert full power signals up to 33 kHz with a sampling fre-

quency of 66 kHz.

T he part features three user-determined input ranges, 0 V to

+5 V, 0 V to 10 V and ±5 V. T hese unipolar and bipolar

ranges are achieved with a 5 V only power supply.

In addition to the traditional dc accuracy specifications such as

linearity, full-scale and offset errors, the AD7880 is also fully

specified for dynamic performance parameters including har-

monic distortion and signal-to-noise ratio.

T he AD7880 is fabricated in Analog Devices’ Linear Compat-

ible CMOS (LC²MOS) process, a mixed technology process

that combines precision bipolar circuits with low power CMOS

logic. T he part is available in a 24-pin, 0.3 inch-wide, plastic or

hermetic dual-in-line package (DIP) as well as a small 24-lead

SOIC package.
