3V, 12-Bit, 150ksps

1- and 2-Channel ADCs in MSOP

FEATURES

DESCRIPTIO

12-Bit 150ksps ADCs in MSOP Package

Single 3V Supply

Low Supply Current: 450µA (Typ)

Auto Shutdown Reduces Supply Current

to 10µA at 1ksps

True Differential Inputs

1-Channel (LTC1860L) or 2-Channel (LTC1861L)

Versions

SPI/MICROWIRE

Compatible Serial I/O

High Speed Upgrade to LTC1285/LTC1288

Pin Compatible with 16-Bit LTC1864L/LTC1865L

No Minimum Data Transfer Rate

The LTC

1860L/LTC1861L are 12-bit A/D converters that

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

single 3V supply. At 150ksps, the supply current is only

450µA. The supply current drops at lower speeds because

the LTC1860L/LTC1861L automatically power down be-

tween conversions. These 12-bit switched capacitor suc-

cessive approximation ADCs include sample-and-holds.

The LTC1860L has a differential analog input with an

external reference pin. The LTC1861L offers a software-

selectable 2-channel MUX and an external reference pin on

the MSOP version.

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.

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.
