Description
The MCP606/7/8/9 family of operational amplifiers (op
amps) from Microchip Technology Inc. are unity-gain
stable with low offset voltage (250 µV, max.).
Performance characteristics include rail-to-rail output
swing capability and low input bias current (80 pA at
+85°C, max.). These features make this family of op
amps well suited for single-supply, precision, high-
impedance, battery-powered applications.
The single MCP606 is available in standard 8-lead
PDIP, SOIC and TSSOP packages, as well as in a
SOT-23-5 package. The single MCP608 with Chip
Select (CS) is offered in standard 8-lead PDIP, SOIC
and TSSOP packages. The dual MCP607 is offered in
standard 8-lead PDIP, SOIC and TSSOP packages.
Finally, the quad MCP609 is offered in standard
14-lead PDIP, SOIC and TSSOP packages. All devices
are fully specified from -40°C to +85°C, with power
supplies from 2.5V to 5.5V.
