LTC1860/LTC1861

µPower, 12-Bit, 250ksps

1- and 2-Channel ADCs in MSOP

FEATURES

DESCRIPTION

The LTC^®1860/LTC1861 are 12-bit A/D converters that are

offeredinMSOPandSO-8packagesandoperateonasingle

5V supply. At 250ksps, the supply current is only 850μA.

The supply current drops at lower speeds because the

LTC1860/LTC1861 automatically power down to a typical

supply current of 1nA between conversions. These 12-bit

switchedcapacitorsuccessiveapproximationADCsinclude

sample-and-holds. The LTC1860 has a differential analog

input with an adjustable reference pin. The LTC1861 offers

a software-selectable 2-channel MUX and an adjustable

reference pin on the MSOP version.

12-Bit 250ksps ADCs in MSOP Package

Single 5V Supply

Low Supply Current: 850μA (Typ)

Auto Shutdown Reduces Supply Current

to 2μA at 1ksps

True Differential Inputs

1-Channel (LTC1860) or 2-Channel (LTC1861)

Versions

SPI/MICROWIRE^TMCompatible Serial I/O

High Speed Upgrade to LTC1286/LTC1298

Pin Compatible with 16-Bit LTC1864/LTC1865

Guaranteed Operation to 125°C (MSOP Package)

The 3-wire, serial I/O, MSOP or SO-8 package and

extremely high sample rate-to-power ratio make these

ADCs ideal choices for compact, low power, high speed

systems.

APPLICATIONS

High Speed Data Acquisition

Portable or Compact Instrumentation

Low Power Battery-Operated Instrumentation

Isolated and/or Remote Data Acquisition

These ADCs can be used in ratiometric applications or

with external references. The high impedance analog in-

puts and the ability to operate with reduced spans down

to 1V full scale, allow direct connection to signal sources

in many applications, eliminating the need for external

gain stages.
