The TPA9361 is a general-purpose, unity-gain difference amplifier, which is intended for precision signal conditioning. The on-chip resistors are trimmed for excellent gain accuracy and high CMRR. It has extremely low-gain drift within the operating temperature range. It also provides an exceptional mon-mode rejection ratio (100 d B typical) and high bandwidth while amplifying signals are well beyond the supply rails. The monmode range of the amplifier extends to almost two times than the supply voltage, making the device ideal for singlesupply applications that require a wide mon-mode voltage range.
