Microchip (MCP3426A0-E/SN) Analogue to Digital Converter, 16 bit,

Analogue to Digital Converter, 16 bit, 15 SPS, Differential, I2C, Single, 2.7 V Product Overview The MCP3426A0-E/SN is a 2-channel low-noise, high accuracy delta-sigma A/D converter IC with differential inputs and up to 16 bits of resolution. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially. The device uses a two-wire I²C™ compatible serial interface and operates from a single power supply ranging from 2.7 to 5.5V. The MCP3426A0-E/SN device performs conversions at rates of 15, 60 or 240 samples per second depending on user controllable configuration bit settings. This device has an onboard programmable gain amplifier (PGA). User can select the PGA gain of x1, x2, x4 or x8 before the analogue-to-digital conversion takes place. This allows the MCP3426A0-E/SN device to convert a smaller input signal with high resolution. The device has two conversion modes (a) continuous mode and (b) one-shot mode. In one-shot mode, the device enters a low current standby mode automatically after one conversion. 16-bit Resolution 2-channel Differential Input Operation Differential Input Operation On-board Voltage Reference with 15ppm/°C Drift On-board PGA, Gains of 1, 2, 4 and 8 15 SPS (16 bits), 60 SPS (14 bits) and 240 SPS (12 bits) Programmable Data Rate Options INL 10ppm of FSR Maximum 135µA (at 3V) Low-current Consumption One-shot or Continuous Conversion Options Supports I²C™ Serial Interface Applications Portable Devices, Consumer Electronics, Sensing & Instrumentation, Industrial, Automation & Process Control Product Information: Resolution (Bits): 16bit Sampling Rate: 15SPS Input Channel Type: Differential Supply Voltage Min: 2.7V Data Interface: I2C Supply Voltage Type: Single Supply Voltage Max: 5.5V ADC / DAC Case Style: SOIC No. of Pins: 8Pins Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: Dual 16-Bit Sigma-Delta ADCs MSL: MSL 1 - Unlimited
