■

The LTC1196/LTC1198 are 600ns, 8-bit A/D converters

with sampling rates up to 1MHz. They are offered in 8-pin

SO packages and operate on 3V to 6V supplies. Power

dissipation is only 10mW with a 3V supply or 50mW with

a 5V supply. The LTC1198 automatically powers down to

a typical supply current of 1nA whenever it is not perform-

ing conversions. These 8-bit switched-capacitor succes-

sive approximation ADCs include sample-and-holds. The

LTC1196 has a differential analog input; the LTC1198

offers a software selectable 2-channel MUX.

■

The 3-wire serial I/O, SO-8 packages, 3V operation and

extremely high sample rate-to-power ratio make these

ADCs an ideal choice for compact, high speed systems.

external references. The high impedance analog inputs

and the ability to operate with reduced spans below 1V full

scale (LTC1196) allow direct connection to signal sources

in many applications, eliminating the need for gain stages.
