MCP661/2/3/5
60 MHz, 6 mA Op Amps
Features
Description
• Gain Bandwidth Product: 60 MHz (typical)
• Short Circuit Current: 90 mA (typical)
• Noise: 6.8 nV/√Hz (typical, at 1 MHz)
• Rail-to-Rail Output
The Microchip Technology, Inc. MCP661/2/3/5 family of
operational amplifiers features high gain bandwidth
product (60 MHz, typical) and high output short circuit
current (90 mA, typical). Some also provide a Chip
Select pin (CS) that supports a low power mode of
operation. These amplifiers are optimized for high
speed, low noise and distortion, single-supply
operation with rail-to-rail output and an input that
includes the negative rail.
• Slew Rate: 32 V/µs (typical)
• Supply Current: 6.0 mA (typical)
• Power Supply: 2.5V to 5.5V
• Extended Temperature Range: -40°C to +125°C
This family is offered in single (MCP661), single with
CS pin (MCP663), dual (MCP662) and dual with
two CS pins (MCP665). All devices are fully specified
from -40°C to +125°C.
