MCP6D11 Operational Amplifiers

The MCP6D11 from Microchip Technology is a low noise, low-distortion differential I/O amplifier optimized for driving high-performance 14- and 16-bit SAR ADCs, such as the MCP331x1D ADC family. Featuring a low 5.0 nV/√Hz input-referred voltage noise and distortion of less than -116 dBc with an input signal of up to 100 kHz (2 VP-P), the MCP6D11 consumes only 3.5 mW of quiescent power on a 2.5 V supply. For power sensitive applications, a power-down function reduces the power consumption to less than 13 µW.

The MCP6D11 is the ideal interface solution for converting single-ended, ground-referenced signal sources into a fully differential output signal required to preserve the high performance of today's ultra-low distortion, single-supply ADCs.
