Description
The MCP6021, MCP6022, MCP6023 and MCP6024
from Microchip Technology Inc. are rail-to-rail input and
output op amps with high performance. Key
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 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 ranges. It has a power
supply range of 2.5V to 5.5V.
