Microchip Technology MCP3425A1T-E/CH
- Part Number:
- MCP3425A1T-E/CH
- Manufacturer:
- Microchip Technology
- Ventron No:
- 3011808-MCP3425A1T-E/CH
- Description:
- IC ADC 16BIT 1CH 15SPS SOT-23-6
- Datasheet:
- MCP3425A1T-E/CH
Description
The MCP3425 is a single-channel, low-noise, high-accuracy AΣ A/D converter with differential inputs and up to 16 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 (A voltage 4.096V). The device uses a two-wire I²C compatible serial interface and operates from a single 2.7V to 5.5V power supply.
Features
16-bit AΣ 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%
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:
15 SPS (16 bits)
60 SPS (14 bits)
240 SPS (12 bits)
One-Shot or Continuous Conversion Options
Low Current Consumption:
145 μA typical (VoD-3V, Continuous Conversion)
One-Shot Conversion (1 SPS) with VDD-3V:
9.7 μA typical with 16 bit mode
2.4 A typical with 14 bit mode
-0.6 μA typical with 12 bit mode
Supports I²C Serial Interface:
Standard, Fast and High-Speed Modes
Single Supply Operation: 2.7V to 5.5V
Extended Temperature Range: -40°C to 125°C
Applications
Portable Instrumentation
Weigh Scales and Fuel Gauges
Temperature Sensing with RTD, Thermistor, and Thermocouple
Bridge Sensing for Pressure, Strain, and Force
