Resistor Ladder (R ) LAD MCP6G01/1R/1U/2/3/4 110 A Selectable Gain Amplifier Features Description 3 Gain Selections: The Microchip Technology Inc. MCP6G01/1R/1U/2/3/4 - +1, +10, +50 V/V are analog Selectable Gain Amplifiers (SGA). They can One Gain Select Input per Amplifier be configured for gains of +1V/V, +10V/V, and +50 V/V through the Gain Select input pin(s). The Chip Rail-to-Rail Input and Output Select pin on the MCP6G03 can put it into shutdown to Low Gain Error: 1% (max.) conserve power. These SGAs are optimized for single High Bandwidth: 250 kHz to 900 kHz (typ.) supply applications requiring reasonable quiescent Low Supply Current: 110 A (typ.) current and speed. Single Supply: 1.8V to 5.5V The single amplifiers MCP6G01, MCP6G01R, Extended Temperature Range: -40C to +125C MCP6G01U, and MCP6G03, are available in 5-pin SOT-23 package and the dual amplifier MCP6G02, are Typical Applications available in 8-pin SOIC and MSOP packages. The quad amplifier MCP6G04 is available in 14-pin SOIC A/D Converter Driver and TSSOP packages. All parts are fully specified from Industrial Instrumentation -40C to +125C.
