Analog & Interface Product Selector Guide

The MCP9700 Thermistor Demo Board 

contains the analog circuitry to measure 

temperature . The board uses BC Components’ 

232264055103 NTC thermistor to convert 

temperature to resistance . The thermistor 

is placed in a voltage divider which converts 

resistance to voltage . This voltage is filtered 

and placed at the MCP6S22 Programmable Gain Amplifier’s 

(PGA) CH0 input . The PGA gains and buffers the thermistor .

This board demonstrates how to bias a 

Resistive Temperature Detector (RTD) 

and accurately measure temperature . 

Up to two RTDs can be connected . 

The RTDs are biased using constant 

current source and the output voltage is scaled using 

a differential amplifier . The output is then connected 

to a 12-bit differential Analog-to-Digital Converter (ADC) 

MCP3301 . The ADC outputs serial data to a PIC18F2550 

device using a Serial Peripheral Interface (SPI) . The data 

is transmitted to a PC using a USB interface . A Microsoft 

Excel® macro is used as a Graphical User Interface (GUI) 

to acquire the data . The acquired data is stored in an Excel 

worksheet and graphed as a real-time strip chart display .

Allows users to store up to 128,000 

temperature readings from the 

MCP9800 sensor to the 24LC1025, 

Microchip’s 1024 Kbit EEPROM . 

A PIC16F684 MCU communicates 

with the sensor and EEPROM . In addition, the PIC MCU 

interfaces to a PC using the PICkit™ 1 Flash Starter Kit 

and transfers the temperature readings from the EEPROM 

to the PC . Microsoft Excel® can be used to view the data .

The MCP3901 and PIC18F65J90 Energy 

Meter Reference Design is a fully functional 

IEC Class 0 .5 compliant single-phase 

meter . This low-cost design does not use 

any transformers and requires few external 

components . The PIC18F65J90 directly 

drives the LCD and includes both an isolated USB 

connection for meter calibration and access to the device 

power calculations . The system calculates active energy, 

active power, RMS current, RMS voltage, reactive energy, 

reactive power, apparent power, and other typical power 

quantities .

This board is used to demonstrate 

the MCP3421 18-bit delta-sigma ADC 

for battery fuel gauging applications . 

It includes two MCP3421 devices, 

MCP73831 (single cell Li-Ion/

Li-Polymer Charger) and PIC18F4550 MCU . The board 

measures: (1) the battery voltage and (2) the current 

coming out from the battery in the discharging mode and 

into the battery in the charging mode using the ADC device 

(if charging mode is enabled (optional)) . It calculates the 

total fuel used and also fuel remaining .

This daughter board demonstrates the 

MCP4725 (12 bit DAC with non-volatile 

memory) features using the Explorer 16 

Development Board and the PICkit Serial 

Analyzer .

The MCP42XX PICtail Plus Daughter 

Board is used to demonstrate the 

operation of the MCP42XX Digital 

Potentiometers . The operation of the 

MCP41XX devices is similar to the MCP42XX devices . 

Therefore, this demo board can be used as a development 

platform for either device family . This board is designed to 

be used in conjunction with either the PIC24 Explorer 16 

Demo Board or the PICkit Serial Analyzer .

This reference design is a complete stand-

alone constant current battery charger for 

NiMH, NiCd or constant current/constant 

voltage for Li-Ion battery packs . When 

charging NiMH or NiCd batteries, the 

reference design is capable of charging one, 

two, three or four batteries connected in series and one 

or two series batteries for Li-Ion . This board utilizes the 

MCP1631HV (high-speed PIC MCU PWM TSSOP-20) and 

PIC16F883 (28-pin SSOP) .

The MCP73871 Demo Board with Voltage 

Proportional Current Control is designed to 

demonstrate Microchip’s stand-alone linear 

Li-Ion battery charger with system power 

path and load sharing management control 

solution . The MCP73871 integrates the required elements 

to meet design challenges when developing new Li-Ion/

Li-Polymer battery powered products .
