The LTC6910-1CTS8#TRMPBF is a digitally controlled Programmable Gain Amplifier that is easy to use and occupy very little PC board space. The inverting gain is adjustable using a 3-bit digital input to select gains of 0, 1, 2, 5, 10, 20, 50 and 100V/V in the LTC6910-1. The LTC6910-1 is inverting amplifier with rail-to-rail output. When operated with unity gain, they will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications. Settling time in the CMOS gain-control logic is typically several nanoseconds and faster than the analogue signal path. Electrically clean construction is important in applications seeking the full dynamic range of the LTC6910-1 amplifier. Short, direct wiring will minimize parasitic capacitance and inductance. Analogue data acquisition can exploit band limiting as well as gain to suppress unwanted signals or noise.
