LT1635 - Micropower Rail-to-Rail Op Amp And Reference
The LT1635 is a new Analog building block that includes a Rail-to-Rail output opamp,a precision reference and reference Buffer The device operates from supplies as low as a single 1.2V or up to 5V, yet it consumes only 130A of supply current. The input common mode range of the op amp includes ground and incorporates phase reversal protection to prevent false outputs from occurring when the input is below the negative supply. The Rail-to-Rail output stage CAN swing to within 15mV of each rail with no load and CAN swing to within 250mV of each rail while delivering 10mA of output current. The gain bandwidth of the op amp is 175kHz and it is unity-gain stable with up to 1000pF load capacitance.
The 0.2V reference is referred to V- and includes a Buffer Amplifier to enhance flexibility. The reference and Buffer combine to achieve a drift of 30ppm/C, a line regulation of 20ppm/ V and a load regulation of 150ppm/mA.
The LT1635 is available in 8-pin PDIP and SOpackages,and has the industry standard LM10 pinout.
