LTC1852/LTC1853

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

400ksps, Low Power, Sampling ADCs

FEATURES

DESCRIPTION

The 10-bit LTC^®1852 and 12-bit LTC1853 are complete

8-channeldataacquisitionsystems.Theyincludeaﬂexible

8-channel multiplexer, a 400ksps successive approxima-

tionanalog-to-digitalconverter,aninternalreferenceanda

paralleloutputinterface.Themultiplexercanbeconﬁgured

forsingle-endedordifferentialinputs,twogainrangesand

unipolar or bipolar operation. The ADCs have a scan mode

thatwillrepeatedlycyclethroughall8multiplexerchannels

and can also be programmed to sequence through up to

16 addresses and conﬁgurations. The sequence can also

be read back from internal memory.

Flexible 8-Channel Multiplexer

Single-Ended or Differential Inputs

Two Gain Ranges

Unipolar or Bipolar Operation

Scan Mode and Programmable Sequencer

Eliminate Conﬁguration Software Overhead

Low Power: 3mW at 250ksps

2.7V to 5.5V Supply Range

Internal or External Reference Operation

Parallel Output Includes MUX Address

Nap and Sleep Shutdown Modes

Pin Compatible up-grade 1.25Msps 10-Bit LTC1850

and 12-Bit LTC1851

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 pow-

ered from a separate supply allowing for easy interface

to 3V digital logic. Typical power consumption is 10mW

at 400ksps from a single 5V supply and 3mW at 250ksps

from a single 3V supply.
