High-Performance, Stand-Alone ADCs for a Variety of Embedded Systems Applications
With 2, 4, and 8 channels that are configurable as either
pseduo-differential or single-ended, the MCP3X02/4/8
converters are versatile and powerful ADCs. Industry-leading
low-power technology offers low current consumption for these
multi-channel devices: <1 µA standby and 250 µA at 100 ksps.
With exceptional INL and DNL performance (±1 LSB) across
broad voltage and temperature ranges (2.7V to 5.5V and -40
to +85°C), multi-channel applications requiring superb linearity
are ideal for these devices.
–
These dual-channel devices are programmable to either
2 pseduo-differential pairs or 4 single-ended inputs.
The quad-channel devices are programmable to provide
4 pseudo-differential pairs or 8 single-ended inputs.
Communication is accomplished using an industry standard
serial SPI™ protocol.
