LTC1864/LTC1865

µPower, 16-Bit, 250ksps

1- and 2-Channel

ADCs in MSOP

FEATURES

DESCRIPTION

The LTC^®1864/LTC1865 are 16-bit A/D converters that

are 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

becausetheLTC1864/LTC1865automaticallypowerdown

between conversions. These 16-bit switched capacitor

successive approximation ADCs include sample-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 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 (LTC1864) or 2-Channel (LTC1865)

Versions

SPI/MICROWIRE™ Compatible Serial I/O

16-Bit Upgrade to 12-Bit LTC1286/LTC1298

Pin Compatible with 12-Bit LTC1860/LTC1861

Guaranteed Operation to +125°C (MSOP Package)

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.

APPLICATIONS

High Speed Data Acquisition

Portable or Compact Instrumentation

Low Power Battery-Operated Instrumentation

Isolated and/or Remote Data Acquisition

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.
