MCP6N11-001E/SN Microchip

MCP6N11 500 kHz, 800 A Instrumentation Amplifier Features Description Rail-to-Rail Input and Output Microchip Technology Inc. offers the single MCP6N11 instrumentation amplifier (INA) with Enable/V Cali- Gain Set by 2 External Resistors OS bration pin (EN/CAL) and several minimum gain Minimum Gain (G ) Options: MIN options. It is optimized for single-supply operation with 1, 2, 5, 10 or 100 V/V rail-to-rail input (no common mode crossover distor- Common Mode Rejection Ratio (CMRR): 115 dB tion) and output performance. (typical, G =100) MIN Two external resistors set the gain, minimizing gain Power Supply Rejection Ratio (PSRR): 112 dB error and drift-over temperature. The reference voltage (typical, G =100) MIN (V ) shifts the output voltage (V ). REF OUT Bandwidth: 500 kHz (typical, Gain = G ) MIN The supply voltage range (1.8V to 5.5V) is low enough Supply Current: 800 A/channel (typical) to support many portable applications. All devices are Single Channel fully specified from -40C to +125C. Enable/V Calibration pin: (EN/CAL) OS These parts have five minimum gain options (1, 2, 5, 10 Power Supply: 1.8V to 5.5V and 100 V/V). This allows the user to optimize the input Extended Temperature Range: -40C to +125C offset voltage and input noise for different applications.
