The LTC6363 family consists of four fully differential, low power, low noise amplifiers with rail-to-rail outputs optimized to drive SAR ADCs. The LTC6363 is a standalone differential amplifier, where the gain is typically set using four external resistors. The LTC6363-0.5, LTC6363-1, and LTC6363-2 each have internal matched resistors to create fixed gain blocks with gains of 0.5V/V, 1V/V, and 2V/V respectively. Each of the fixed-gain amplifiers features precision laser trimmed on-chip resistors for accurate, ultrastable gain and excellent CMRR.
Applications
- 20-Bit, 18-Bit and 16-Bit SAR ADC Drivers
- Single-Ended-to-Differential Conversion
- Low Power ADC Drivers
- Level Shifter
- Differential Line Drivers
- Battery-Powered Instrumentation

DC2655A
LTC6363-1, LTC6363-2, LTC6363-0.5 Fully Differential Amplifier
Product Detail
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.

DC2487A
LTC6363 Rail-to-Rail SAR ADC Driver Amplifier
Product Detail
Demonstration circuit 2487A features the LTC6363 amplifier. The DC2487A is designed to drive the inputs of the DC2290A demo board. The DC2290A features the LTC2387 18-bit, 15Msps high speed SAR ADC. The linearity and low noise of the LTC6363 make it an ideal candidate to drive the LTC2387 at frequencies up to 100kHz.

DC2319A-A
LTC6363 Differential Op Amp/ADC Driver Demo Board
Product Detail
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.
