A Click accessory module for use with MikroElektronika mikroBUS microcontroller development boards. The GainAMP click board is equipped with a Linear Technology LTC®6912-1 dual channel, low noise, digitally programmable gain amplifier (PGA). The two channels of the PGA can be independently programmed for inverting gains of 0, 1, 2, 5, 10, 20, 50, and 100V/V via SPI interface. The click board includes three pairs of screw terminals and a power indication LED and can be operated from either a 3.3V or 5V power supply.
