SOT-23-THN (DDF)-8-8.12 mm² 2.9 x 2.8
The INA151 is a precision voltage monitoring amplifier with an input common-mode voltage range of up to 110V above negative supply (recommended). The INA151 can accurately measure voltages in the presence of high common-mode voltage with a high common-mode rejection ratio of 125dB minimum and input impedance of >1.4MΩ and an offset voltage drift of 0.6µV/ºC.
The INA151A version offers gain option of 1V/V, while the INA151B and INA151C and INA151D versions offer gain options of 0.66V/V, 0.5V/V and 0.25V/V respectively.
The INA151 has an Enable/Disable pin that provide a high-impedance output to allow stacking multiple INA151 on the outputs. In many applications this omit the need for an input multiplexer.
The INA151 is offered in standard 8-pin packages such as SOT-23.
