MCP6421

4.4 µA, 90 kHz Op Amp

Features:

Description:

The Microchip Technology Inc. MCP6421 family of

operational amplifiers operate with a single supply

voltage as low as 1.8V, while drawing low quiescent

current per amplifier (5.5 µA, maximum). This family

also has low input offset voltage (±1.0 mV, maximum)

and rail-to-rail input and output operation. In addition,

the MCP6421 family is unity gain stable and has a gain

bandwidth product of 90 kHz (typical). This

combination of features supports battery-powered and

portable applications. The MCP6421 family has

enhanced EMI protection to minimize any

electromagnetic interference from external sources,

such as power lines, radio stations, and mobile

communications, etc. This feature makes it well suited

for EMI sensitive applications.

• Low Quiescent Current:

- 4.4 µA/amplifier (typical)

• Low Input Offset Voltage:

- ±1.0 mV (maximum)

• Enhanced EMI Protection:

- Electromagnetic Interference Rejection Ratio

(EMIRR) at 1.8 GHz: 97 dB

• Supply Voltage Range: 1.8V to 5.5V

• Gain Bandwidth Product: 90 kHz (typical)

• Rail-to-Rail Input/Output

• Slew Rate: 0.05 V/µs (typical)

• Unity Gain Stable

• No Phase Reversal

• Small Packages:

The MCP6421 family is offered in single (MCP6421)

packages. All devices are designed using an advanced

CMOS process and fully specified in extended

temperature range from -40°C to +125°C.

- Singles in SC70-5, SOT-23-5

• Extended Temperature Range:

- -40°C to +125°C
