General Description
The MCP3421 is a single channel low-noise, high accuracy ΔΣ A/D converter with differential inputs and up to 18 bits of resolution in a small SOT-23-6 package.
The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially (Δ voltage = 4.096V).
Key Features
- 18-bit ΔΣ ADC in a SOT-23-6 package.
- Differential input operation.
- Self calibration of Internal Offset and Gain per each conversion.
- On-board Voltage Reference: - Accuracy: 2.048V ± 0.05% - Drift: 5 ppm/°C.
- On-board Programmable Gain Amplifier (PGA): - Gains of 1,2,4 or 8.
- On-board Oscillator.
- INL: 10 ppm of FSR (FSR = 4.096V/PGA).
- Programmable Data Rate Options: - 3.75 SPS (18 bits) - 15 SPS (16 bits) - 60 SPS (14 bits) -.
