MCP601/602/603/604
2.7V to 5.5V Single Supply CMOS Op Amps
ates with a single supply voltage that can be as low as
2.7V, while drawing less than 325µA of quiescent cur-
rent. In addition, the common-mode input voltage
range goes 0.3V below ground, making these amplifi-
ers ideal for single supply operation.
FEATURES
• Specifications rated from 2.7V to 5.5V supplies
• Rail-to-rail swing at output
• Common-mode input swing below ground
• 2.8MHz GBWP
These devices are appropriate for low-power battery
operated circuits due to the low quiescent current, for
A/D Converter driver amplifiers because of their wide
bandwidth, or for anti-aliasing filters by virtue of their
low input bias current.
• Unity gain stable
• Low power IDD = 325µA max
• Chip Select capability with MCP603
• Industrial temperature range (-40°C to 85°C)
• Available in single, dual and quad
The MCP601, MCP602 and MCP603 are available in
standard 8-lead PDIP, SOIC and TSSOP packages.
The MCP601 is also available in the SOT23-5 pack-
age. The quad MCP604 is offered in 14-lead PDIP,
SOIC and TSSOP packages. PDIP and SOIC pack-
ages are fully specified from -40°C to +85°C with power
supplies from 2.7V to 5.5V.
