The LMP7702MA/NOPB is a high performance, low power, low noise Programmable Gain Amplifier from Texas Instruments. This device is available in a 4-pin SOT-23 package with an adjustable gain from -1 V/V to +45V/V. It also features :
• Low power operation : 50uA,
• Low noise – 8.2nV/v Hz at 1kHz,
• High CMRR – 80dB typical at 1kHz,
• Low offset voltage — 10mV typical,
• High output current capable of driving 100mA.
This device is suitable for a variety of signal-processing applications, such as bio-sensing, acoustic sensors, and data converters. It also minimizes crosstalk and interference among multiple gain stages.
