- Manufacturer:
- Microchip Technology
- Ventron No:
- 3011399-MCP3422A2T-E/MC
- Description:
- IC ADC 18BIT 2CH 3.75SPS 8DFN
- Datasheet:
- MCP3422A2T-E/MC
Description
The MCP3422/3/4 devices are 18-bit, multi-channel analog-to-digital converters (ADCs) with a differential input range of ±2.048V. They feature an on-board 2.048V reference voltage, a programmable gain amplifier (PGA), and a two-wire I2C serial interface. The devices can operate from a single 2.7V to 5.5V power supply and have a low current consumption of 135 μA (typical) in continuous conversion mode.
Features
18-bit resolution
Differential input range: ±2.048V
On-board 2.048V reference voltage (accuracy: ±0.05%, drift: 15 ppm/°C)
Programmable gain amplifier (PGA): gains of 1, 2, 4, or 8
Programmable data rate options: 3.75, 15, 60, or 240 samples per second
One-shot or continuous conversion modes
Low current consumption: 135 μA (typical) in continuous conversion mode
On-board oscillator
I2C interface: standard, fast, and high-speed modes
User-configurable external address pins for MCP3423 and MCP3424
Single supply operation: 2.7V to 5.5V
Extended temperature range: -40°C to 125°C
Applications
Portable instrumentation and consumer goods
Temperature sensing with RTD, thermistor, and thermocouple
Bridge sensing for pressure, strain, and force
Weigh scales
Battery fuel gauges
Factory automation equipment
