GENERAL D ESCRIP TIO N

T he AD7870/AD7875/AD7876 is a fast, complete, 12-bit A/D

converter. It consists of a track/hold amplifier, 8 µs successive-

approximation ADC, 3 V buried Zener reference and versatile

interface logic. T he ADC features a self-contained internal

clock which is laser trimmed to guarantee accurate control of

conversion time. No external clock timing components are re-

quired; the on-chip clock may he overridden by an external

clock if required.

1. Complete 12-Bit ADC on a Chip.

T he AD7870/AD7875/AD7876 provides all the functions

necessary for analog-to-digital conversion and combines a

12-bit ADC with internal clock, track/hold amplifier and

reference on a single chip.

2. Dynamic Specifications for DSP Users.

T he parts offer a choice of three data output formats: a single,

parallel, 12-bit word; two 8-bit bytes or serial data. Fast bus ac-

cess times and standard control inputs ensure easy interfacing to

modern microprocessors and digital signal processors.

T he AD7870 and AD7875 are fully specified and tested for

ac parameters, including signal-to-noise ratio, harmonic dis-

tortion and intermodulation distortion.

3. Fast Microprocessor Interface.

All parts operate from ±5 V power supplies. T he AD7870 and

AD7876 accept input signal ranges of ±3 V and ±10 V, respec-

tively, while the AD7875 accepts a unipolar 0 V to +5 V input

range. T he parts can convert full power signals up to 50 kHz.

Data access times of 57 ns make the parts compatible with

modern 8- and 16-bit microprocessors and digital signal pro-

cessors. Key digital timing parameters are tested and guaran-

teed over the full operating temperature range.

T he AD7870/AD7875/AD7876 feature dc accuracy specifica-

tions such as linearity, full-scale and offset error. In addition,

the AD7870 and AD7875 are fully specified for dynamic perfor-

mance parameters including distortion and signal-to-noise ratio.

T he parts are available in a 24-pin, 0.3 inch-wide, plastic or her-

metic dual-in-line package (DIP). T he AD7870 and AD7875

are available in a 28-pin plastic leaded chip carrier (PLCC),

while the AD7876 is available and in a 24-pin small outline

(SOIC) package.
