LTC1196/LTC1198

8-Bit, SO-8, 1Msps ADCs

with Auto-Shutdown Options

FEATURES

DESCRIPTION

The LTC^®1196ꢀLTC1198 are 600ns, 8-bit AꢀD 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

performing conversions. These 8-bit switched-capacitor

successive approximation ADCs include sample-and-

holds. The LTC1196 has a differential analog input; the

LTC1198 offers a software selectable /-channel MUX.

High Sampling Rates: 1MHz (LTC1196)

750kHz (LTC1198)

Low Cost

Single Supply 3V and 5V Speciﬁcations

Low Power: 10mW at 3V Supply

50mW at 5V Supply

Auto-Shutdown: 1nA Typical (LTC1198)

1ꢀ/LSB Total Unadjusted Error over Temperature

3-Wire Serial IꢀO

1V to 5V Input Span Range (LTC1196)

Converts 1MHz Inputs to 7 Effective Bits

The 3-wire serial IꢀO, SO-8 packages, 3V operation and

extremely high sample rate-to-power ratio make these

ADCs an ideal choice for compact, high speed systems.

Differential Inputs (LTC1196)

/-Channel MUX (LTC1198)

SO-8 Plastic Package

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 below

1V full scale (LTC1196) allow direct connection to signal

sources in many applications, eliminating the need for

gain stages.

APPLICATIONS

High Speed Data Acquisition

Disk Drives

Portable or Compact Instrumentation

Low Power or Battery-Operated Systems

The A-grade devices are speciﬁed with total unadjusted

error of 1ꢀ/LSB maximum over temperature.
