LTC1850/LTC1851

8-Channel, 10-Bit/12-Bit,

1.25Msps Sampling ADCs

FEATURES

DESCRIPTIO

The 10-bit LTC^®1850 and 12-bit LTC1851 are complete

8-channel data acquisition systems. They include a flex-

ible8-channelmultiplexer,a1.25Mspssuccessiveapproxi-

mation analog-to-digital converter with sample-and-hold,

an internal 2.5V reference and reference buffer amplifier,

andaparalleloutputinterface. Themultiplexercanbecon-

figured for single-ended or differential inputs, two gain

ranges and unipolar or bipolar operation.

Operation

1.25Msps Sampling Rate

■

Single 5V Supply and 40mW Power Dissipation

■

Scan Mode and Programmable Sequencer

■

Pin Compatible 10-Bit LTC1850 and 12-Bit LTC1851

■

True Differential Inputs Reject Common Mode Noise

The ADCs have a scan mode that will repeatedly cycle

through all 8 multiplexer channels and can also be

programmed with a sequence of up to 16 addresses and

configurations that can be scanned in succession. The

sequence memory can also be read back. The reference

and buffer amplifier provide pin strappable ranges of

4.096V, 2.5V and 2.048V. The parallel output includes

the 10-bit or 12-bit conversion result plus the 4-bit

multiplexer address. The digital outputs are powered

from a separate supply allowing for easy interface to 3V

digital logic. Typical power consumption is 40mW at

1.25Msps from a single 5V supply.
