General Description
The MCP3301 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.
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
permits 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.

Note 1: This specification is established by characterization and not 100% tested.
2: See characterization graphs that relate converter performance to VREF level.
3: VIN = 0.1V to 4.9V @ 1 kHz.
4: VDD = 5V DC ±500 mVP-P @ 1 kHz, see test circuit Figure 1-4.
5: Maximum clock frequency specification must be met.
6: VREF = 400 mV, VIN = 0.1V to 4.9V @ 1 kHz
7: MSOP devices are only specified at 25°C and +85°C.
8: For slow sample rates, see Section 5.2.1 “Maintaining Minimum Clock Speed” for limitations on clock frequency.
9: 4.5V - 5.5V is the supply voltage range for specified performance
