LTC1283

3V Single Chip 10-Bit Data

Acquisition System

DESCRIPTIO

EATURE

Single Supply 3.3V or 3.3V Operation

Software Programmable Features:

Unipolar/Bipolar Conversions

■

The LTC1283 is a 3V data acquisition component which

contains a serial I/O successive approximation A/D con-

verter. It uses LTCMOS^TMswitched capacitor technology

to perform either 10-bit unipolar, or 9-bit plus sign bipolar

A/D conversions. The 8-channel input multiplexer can be

configuredforeithersingle-endedordifferentialinputs(or

combinations thereof). An on-chip sample-and-hold is

included for all single-ended input channels.

Built-In Sample-and-Hold

Direct 4-Wire Interface to Most MPU Serial Ports

and all MPU Parallel Ports

The serial I/O is designed to be compatible with industry-

standardfull-duplexserialinterfaces.ItallowseitherMSB-

or LSB-first data and automatically provides 2’s comple-

ment output coding in the bipolar mode. The output data

word can be programmed for a length of 8-, 10-, 12-, or

16-bit. This allows easy interface to shift registers and a

variety of processors.

Minimum Guaranteed Supply Voltage: 3V

Resolution: 10 Bits

Offset Error: 0.5LSB Max

Linearity Error: 0.5LSB Max

Gain Error (LTC1283A): 1LSB Max

Conversion Time: 44μs

Supply Current: 350μA Max, 150μA Typ

■

Both the LTC1283A and LTC1283 are specified with offset

and linearity errors less than 0.5LSB. The LTC1283A has

a gain error limit of 1LSB. The 1283 is specified with a

gain error limit of 2LSB for applications where gain is

adjustable or less critcial.
