Description:

Microchip Technology Inc. offers the single Zero-Drift MCP6N16 instrumentation amplifier (INA) with Enable pin (EN) and three minimum gain options (GMIN). The internal offset correction gives high DC precision: it has very low offset and offset drift, and negligible 1/f noise.

Features:

• High DC Precision:

- VOS: ±17 µV (maximum, GMIN = 100)

- TC1: ±60 nV/°C (maximum, GMIN = 100)

- CMRR: 112 dB (minimum, GMIN = 100,

VDD = 5.5V)

- PSRR: 110 dB (minimum, GMIN = 100,

VDD = 5.5V)

- gE: ±0.15 (maximum, GMIN = 10, 100)

• Flexible:

- Minimum Gain (GMIN) Options:

1, 10 and 100 V/V

- Rail-to-Rail Input and Output

- Gain Set by Two External Resistors

• Bandwidth: 500 kHz (typical, Gain = GMIN = 1, 10)

• Power Supply:

- VDD: 1.8V to 5.5V

- IQ: 1.1 mA (typical)

- Power Savings (Enable) Pin: EN

• Enhanced EMI Protection:

- Electromagnetic Interference Rejection Ratio

(EMIRR): 111 dB at 2.4 GHz

• Extended Temperature Range: -40°C to +125°C

Typical Applications:

• High-Side Current Sensor

• Wheatstone Bridge Sensors

• Difference Amplifier with Level Shifting

• Power Control Loops

Design Aids:

• SPICE Macro Model

• Microchip Advanced Part Selector (MAPS)
