Description
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 µA and
1 µA, 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-wire I
and Fast (400 kHz) I
device. An on-chip conversion clock enables indepen-
dent timing for the I
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.
