MCP6D11 Low-Noise, Precision, 90 MHz Differential I/O Amplifier Features General Description Low Power The MCP6D11 from Microchip Technology is a low- noise, low-distortion Differential I/O Amplifier optimized -I : 1.4 mA Q for driving high-performance 14-, and 16-Bit SAR - Supply Voltage Range: 2.5V to 5.5V ADCs, such as the MCP331x1D ADC family. Featuring Gain-Bandwidth Product: 90 MHz a low 5.0 nV/Hz input-referred voltage noise and dis- Slew Rate: 25V/s tortion of less than -116 dBc with an input signal of up Low Noise: 5.0 nV/Hz, f = 10 kHz to 100kHz (2Vpp), the MCP6D11 consumes only Low Distortion (2V , 10 kHz): 3.5 mW of quiescent power on a 2.5V supply. For p-p power sensitive applications, a Power-Down function - HD2: -138 dBc reduces the power consumption to less than 13 W. - HD3: -137 dBc pin, the MCP6D11 allows easy Through its V Fast Settling: 200 ns to 0.01% OCM control of its output common-mode voltage, which can Low Offset: 150 V Max. be set independently of the input common-mode Power-Down Function voltage. This, coupled with an input common-mode Input Vcm-Range Includes Negative Rail range that extends below the negative supply rail, and Rail-to-Rail Output a near rail-to-rail output swing capability, results in a simple driver amplifier solution for a variety of ADCs. Small Packages: MSOP-8, 3 x 3 mm QFN-16 Extended Temperature Range: -40C to +125C The MCP6D11 is the ideal interface solution for converting single-ended, ground-referenced signal sources into a fully differential output signal required to Typical Applications preserve the high performance of todays ultra-low Precision ADC Driver: distortion, single-supply ADCs. - 14/16/18-bit SAR ADCs The MCP6D11 is specified for the -40C to +125C - Delta-Sigma ADCs temperature range and is available in QFN-16 Single-Ended to Differential Conversion (3 x 3 mm) and MSOP-8 package options.
