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

Analogue to Digital Converter, 16 bit, 15 SPS, Differential, I2C, Single, 2.7 VProduct OverviewThe MCP3426A0-E/SN is a 2-channel low-noise, high accuracy delta-sigma A/Dconverter IC with differential inputs and up to 16 bits of resolution. Theon-board precision 2.048V reference voltage enables an input range of ±2.048Vdifferentially. The device uses a two-wire I²C compatible serial interface andoperates from a single power supply ranging from 2.7 to 5.5V. The MCP3426A0-E/SNdevice performs conversions at rates of 15, 60 or 240 samples per seconddepending on user controllable configuration bit settings. This device has anonboard 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 allowsthe MCP3426A0-E/SN device to convert a smaller input signal with highresolution. 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 modeautomatically after one conversion.16-bit Resolution2-channel Differential Input OperationDifferential Input OperationOn-board Voltage Reference with 15ppm/°C DriftOn-board PGA, Gains of 1, 2, 4 and 815 SPS (16 bits), 60 SPS (14 bits) and 240 SPS (12 bits) Programmable Data RateOptionsINL 10ppm of FSR Maximum135µA (at 3V) Low-current ConsumptionOne-shot or Continuous Conversion OptionsSupports I²C Serial InterfaceApplicationsPortable Devices, Consumer Electronics, Sensing & Instrumentation, Industrial,Automation & Process ControlProduct Information:Resolution (Bits): 16bitSampling Rate: 15SPSInput Channel Type: DifferentialSupply Voltage Min: 2.7VData Interface: I2CSupply Voltage Type: SingleSupply Voltage Max: 5.5VADC / DAC Case Style: SOICNo. of Pins: 8PinsOperating Temperature Min: -40°COperating Temperature Max: 125°CProduct Range: Dual 16-Bit Sigma-Delta ADCsMSL: MSL 1 - Unlimited
