They are offered in 8-pin SO packages and operate on 3V to 6V supplies. Power dissipation is only 10m W with a 3V supply or 50m W with a 5V supply. The LTC1198 automatically powers down to a typical supply current of 1n A whenever it is not performing conversions. These 8-bit switched-capacitor successive approximation ADCs include sample-andholds. 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 pact, 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 below 1V full scale (LTC1196) allow direct connection to signal sources in many applications, eliminating the need for gain stages. The A-grade devices are specified with total unadjusted error of ±1/2LSB maximum over temperature.
