General Description
The Microchip Technology Inc. MCP3302/04 13-bit A/D
converters feature full differential inputs and low-power
consumption in a small package that is ideal for battery
powered systems and remote data acquisition
applications. The MCP3302 is programmable to
provide two differential input pairs or four single ended
inputs. The MCP3304 is programmable and provides
four differential input pairs or eight single ended inputs.
Incorporating a successive approximation architecture
with on-board sample and hold circuitry, these 13-bit
A/D converters are specified to have ±1 LSB
Differential
Nonlinearity (INL) for B-grade and ±2 LSB for C-grade
devices. The industry-standard SPI serial interface
enables 13-bit A/D converter capability to be added to
any PIC
The MCP3302/04 devices feature low current design
that permits operation with typical standby and active
currents of only 50 nA and 300 µA, respectively. The
devices operate over a broad voltage range of 2.7V to
5.5V and are capable of conversion rates of up to
100 ksps. The reference voltage can be varied from
400 mV to 5V, yielding input-referred resolution
between 98 µV and 1.22 mV.
The MCP3302 is available in 14-pin PDIP, 150 mil
SOIC and TSSOP packages. The MCP3304 is
available in 16-pin PDIP and 150 mil SOIC packages.
The full differential inputs of these devices enable a
wide variety of signals to be used in applications such
as remote data acquisition, portable instrumentation,
and battery operated applications.
