General Description
The MCP3301 13-bit analog-to-digital (A/D) converter
features full differential inputs and low power consump-
tion in a small package that is ideal for battery-powered
systems and remote data acquisition applications.
Incorporating a successive approximation architecture
with on-board sample and hold circuitry, the 13-bit A/D
converter is specified to have ±1 LSB Differential Non-
linearity (DNL) and ±1 LSB Integral Nonlinearity (INL)
for B-grade devices 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 MCP3301 features a low current design that per-
mits operation with typical standby and active currents
of only 50 nA and 300 µA, 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 µV
and 1.22 mV.
The MCP3301 is available in 8-pin PDIP, 150 mil SOIC,
and MSOP packages. The full differential inputs of this
device enable a wide variety of signals to be used in
applications such as remote data acquisition, portable
instrumentation, and battery-operated applications.
