The LTC1272 operates with a single 5V supply but can also accept the 5V/–15V supplies required by the AD7572 (Pin 23, the negative supply pin of the AD7572, is not connected on the LTC1272). The LTC1272 has the same 0V to 5V input range as the AD7572 but, to achieve single supply operation, it provides a 2.42V reference output instead of the – 5.25V of the AD7572.
