General Description
The MCP3302/04 13-bit A/D converter features 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 user-programmable to provide two
differential input pairs or four single-ended inputs.
The MCP3304 is also user-programmable to configure
into 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 (DNL); ±1 LSB Integral
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 microcontroller.
The MCP3302/04 devices feature low current design
that permits operation with typical standby and active
currents of only 50 nA and 300 A, respectively. The
device is capable of conversion rates of up to 100 ksps
with tested specifications over a 4.5V to 5.5V supply
range. The reference voltage can be varied from
400 mV to 5V, yielding input-referred resolution
between 98 V 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.
