18-Bi T Analog- To-Digi Tal Conve R T E R 2 With I C Interface And On-Board Reference

MCP3421 The MCP3421 is a single channel low-noise, high accuracy 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 differentiall 2 ( voltage = 4.096V). The device uses a two-wire I C compatible serial Interface and operates from a single 2.7V to 5.5V power supply. The MCP3421 device performs conversion at rates of 3.75, 15, 60, or 240 samples per second (SPS) depending on the user controllable configuration bit 2 settings using the two-wire I C serial Interface This device has an on-board Programmable Gain Amplifier (PGA). The user CAN select the PGA gain of x1, x2, x4, or x8 before the Analog-to-digital conversion takes place. This allows the MCP3421 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. This reduces current consumption greatly during idle periods. By Microchip Technology Inc.
