2 Low Power 10-Bit A/D Converter With I C? Interface

MCP3021 The Microchip Technology Inc. MCP3021 is a succes- sive approximation A/D converter (ADC) with 10-bit resolution. Available in the SOT-23 package, this device provides one single-ended input with very low power consumption. Based on an advanced CMOS technology, the MCP3021 provides a low maximum conversion current and standby current of 250 A an 1 A, respectively. Low current consumption, com bined with the small SOT-23 package, make this device ideal for battery-powered and remote data acquisition applications. Communication to the MCP3021 is performed using a 2 2-wire I C compatible Interface Standard (100 kHz) 2 and Fast (400 kHz) I C modes are available with the device. An on-chip conversion Clock enables indepen- 2 dent Timing for the I C and conversion Clocks The device is also addressable, allowing up to eight devices on a single 2-wire bus. The MCP3021 runs on a single supply voltage that operates over a broad range of 2.7V to 5.5V. This device also provides excellent linearity of 1 LSB differ ential non-linearity (DNL) and 1 LSB integral non linearity (INL), maximum. By Microchip Technology Inc.
