LTC1864/LTC1865

µPower, 16-Bit, 250ksps

1- and 2-Channel ADCs in MSOP

FEATURES

DESCRIPTIO

TheLTC^®1864/LTC1865are16-bitA/Dconvertersthatare

offered in MSOP and SO-8 packages and operate on a

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

850µA. The supply current drops at lower speeds because

the LTC1864/LTC1865 automatically power down

between conversions. These 16-bit switched capacitor

successiveapproximationADCsincludesample-and-holds.

The LTC1864 has a differential analog input with an

adjustable reference pin. The LTC1865 offers a software-

selectable 2-channel MUX and an adjustable reference pin

on the MSOP version.

16-Bit Upgrade to 12-Bit LTC1286/LTC1298

■

Pin Compatible with 12-Bit LTC1860/LTC1861

The 3-wire, serial I/O, small 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.

APPLICATIO S

■

High Speed Data Acquisition

■

Portable or Compact Instrumentation

These ADCs can be used in ratiometric applications or

with external references. The high impedance analog

inputs 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.

■

Low Power Battery-Operated Instrumentation

Isolated and/or Remote Data Acquisition
