MCP651/1S/2/3/4/5/9
50 MHz, 200 µV Op Amps with mCal
Features:
Description:
• Gain-Bandwidth Product: 50 MHz
• Slew Rate: 30 V/µs
The Microchip Technology Inc. MCP651/1S/2/3/4/5/9
family of high bandwidth and high slew rate operational
amplifiers features low offset. At power-up, these op
amps are self-calibrated using mCal. Some package
options also provide a Calibration/Chip Select pin
• Low Input Offset: ±200 µV (maximum)
• Low Input Bias Current: 6 pA (typical)
• Noise: 7.5 nV/Hz, at 1 MHz
• Ease-of-Use:
(CAL/CS) that supports
a Low-Power mode of
operation, with offset calibration at the time normal
operation is re-started. 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.
- Unity-Gain Stable
- Rail-to-Rail Output
- Input Range incl. Negative Rail
- No Phase Reversal
This family is offered in single (MCP651 and
MCP651S), single with CAL/CS pin (MCP653), dual
(MCP652), dual with CAL/CS pins (MCP655), quad
(MCP654) and quad with CAL/CS pins (MCP659). All
devices are fully specified from -40°C to +125°C.
• Supply Voltage Range: +2.5V to +5.5V
• High Output Current: ±100 mA
• Supply Current: 6.0 mA/Ch (typical)
• Low-Power Mode: 5 µA/Ch
• Small Packages: SOT23-5, DFN
• Extended Temperature Range: -40°C to +125°C
