DC2655A

LTC6363-1, LTC6363-2, LTC6363-0.5 Fully Differential Amplifier

Buy Now View Details

Product Details

The LTC®6363-1, LTC6363-2, LTC6363-0.5 are low power, low noise differential op amps with built-in precision resistors to establish accurate gains of 1, 2 or 0.5 respectively

The DC2655A is a small-size demo circuit that minimizes trace resistance in series with the IC, so that the precise gain and CMRR can be maintained. The board’s inputs can be driven single-ended or differentially. The signal path from inputs to outputs is DC-coupled. An onboard jumper configures the DC2655A for dual or single power supply. To minimize PCB layout parasitics, the configurability of this board has been minimized. For a more flexible board refer to the DC2319A.

Product Details

The LTC6363 is a low power, low noise differential op amp with rail-to-rail output swing and good DC accuracy. The amplifier may be configured to process a fully differential input signal or to convert a single-ended input signal to a differential output signal. The differential outputs of the DC2319A can be configured with a first order RC network for driving the differential inputs of an ADC.
