3、s Audio Processing Communications DAC Buffer Test Equipment Medical Instrumentation Available Tools SPICE Macro Model (at ) FilterLab software (at ) Description The MCP6021, MCP6022, MCP6023 and MCP6024 from Microchip Technology Inc. are rail-to-rail input and output op amps with high performance. K
4、ey specifications include: wide bandwidth (10 MHz), low noise (8.7 nV/Hz), low input offset voltage and low distortion (0.00053% THD+N). These features make these op amps well suited for applications requiring high performance and bandwidth. The MCP6023 also offers a chip select pin (CS) that gives
5、power savings when the part is not in use. The single MCP6021, single MCP6023 and dual MCP6022 are available in standard 8-lead PDIP, SOIC and TSSOP. The quad MCP6024 is offered in 14-lead PDIP, SOIC and TSSOP packages. The MCP6021/2/3/4 family is available in the Industrial and Extended temperature
6、 ranges. It has a power supply range of 2.5V to 5.5V.
