The LTC®2351 14-/12-bit SAR ADCs offer six simultaneously sampling inputs which can be configured to sample from one
differential input at 1.5Msps to six differential inputs at 250ksps. With its low power, small package size and flexible differential
inputs, the LTC2351 is ideal for a range of applications, including multiphase power measurement, multiphase motor control, data
acquisition systems and uninterruptible power supplies.

The LTC®2356 family offers 14-/12-bit resolution, 3.5Msps throughput, bipolar (LTC2356) or unipolar (LTC2355) inputs and a
serial SPI interface. The unique combination of speed, low power, internal reference and small 10-pin MSOP package makes
the LTC2356 family ideal for high speed, portable applications including communications, medical instrumentation and data
acquisition.

The LTC®2366 family of SAR ADCs offers sampling rates from 100ksps to 3Msps in pin-compatible 6- and 8-lead SOT-23
packages. With high impedance, single-ended analog inputs and the ability to operate with reduced spans, these ADCs can
connect directly to sensors and transducers without the need for gain stages. The high sample-rate-to-power ratio makes these
ADCs ideal for compact, low power, high speed systems.

C Interfaces
The LTC®2309 12-bit SAR ADC family offers throughput rates up to 500ksps with an SPI interface and up to 14ksps with an I2C
interface. Featuring an 8-channel integrated multiplexer, these ADCs can measure up to 8 single-ended inputs, 4 differential inputs,
or a combination of both. Operating from a 5V supply, they dissipate only 17mW at 500ksps and 1.5mW at 1ksps throughput.
