General Description
The Microchip Technology Inc. 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, this 13-bit A/
D converter is specified to have 鹵1 LSB Differential
Nonlinearity (DNL) and 鹵1 LSB Integral Nonlinearity
(INL) for B-grade devices and 鹵2 LSB for C-grade
devices. The industry-standard SPI鈩?serial interface
enables 13-bit A/D converter capability to be added to
any PICmicro
廬
microcontroller.
The MCP3301 features a low current design that per-
mits operation with typical standby and active currents
of only 50 nA and 300 碌A(chǔ), respectively. The device
operates over a broad voltage range of 2.7V to 5.5V
and is 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 碌V
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.
