MCP3911 ADC Evaluation Board for 16-bit MCUs
(ADM00398)
The MCP3911 ADC Evaluation Board for
16-Bit MCUs system provides the ability to
evaluate the performance of the MCP3911
dual-channel ADC. It also provides a
development platform for 16-bit PIC-based applications,
using existing 100-pin PIM systems compatible with the
Explorer-16 and other high pin count PIC demo boards. The
system comes with a programmed PIC24FJ256GA110 PIM
module that communicates with the included PC software
for data exchange and ADC configuration.
MCP3421 Weight Scale Demo Board
(MCP3421DM-WS)
The MCP3421 Weight Scale Demo Board
is designed to evaluate the performance
of the low-power consumption, 18-bit
ADC in an electronic weight scale design.
Next to the MCP3421 there is a low-
noise, auto-zero MCP6V07 op amp. This
can be used to investigate the impact
of extra gain added before the ADC for performance
improvement. The PIC18F4550 is controlling the LCD and
the USB communication with the PC. The GUI is used to
indicate the performance parameters of the design and for
calibration of the weight scale.
MCP3421 Battery Fuel Gage Demo Board
(MCP3421DM-BFG)
The MCP3421 Battery Fuel Gauge
Demo Board demonstrates how to
measure the battery voltage and
discharging current using the MCP3421.
The MCU algorithm calculates the
battery fuel being used. This demo board is shipped
with 1.5V AAA non-rechargeable battery. The demo board
displays the following parameters:
(a) Measured battery voltage.
(b) Measured battery discharging current.
(c) Battery Fuel Used (calculated).
The MCP3421 Battery Fuel Gauge Demo Board also can
charge a single-cell 4.2V
Li-Ion battery. This feature, however, is disabled by
firmware since the demo kit is shipped to customer with
non-rechargeable 1.5V AAA battery.
DACs
MCP4725 PICtail Plus Daughter Board
(MCP4725DM-PTPLS)
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.
MCP4725 SOT-23-6 Evaluation Board
(MCP4725EV)
The MCP4725 SOT-23-6 Evaluation
Board is a quick and easy evaluation
tool for the MCP4725 12-bit DAC
device. It works with Microchip’s
popular PICkit Serial Analyzer or independently with the
customer’s applications board. The PICkit Serial Analyzer
is sold separately.
MCP4728 Evaluation Board (MCP4728EV)
The MCP4728 Evaluation Board is a tool for
quick and easy evaluation of the MCP4728
4-channel 12-bit DAC device. It contains the
MCP4728 device and connection pins for the
Microchip’s popular PICkit SerialAnalyzer. The
PICkit Serial Analyzer is sold separately.
Digital Potentiometers
MCP42XX PICtail Plus Daughter Board
(MCP42XXDM-TPTLS)
The MCP42XX PICtail Plus Daughter
Board is used to demonstrate the
operation of the MCP42XX Digital
Potentiometers. This board is
designed to be used in conjunction
with either the PIC24 Explorer 16 Demo Board or the
PICkit Serial Analyzer.
MCP402X Non-Volatile Digital Potentiometer
Evaluation Board (MCP402XEV)
The MCP402XEV is a low cost
evaluation board that quickly enables
the user to exercise all of the features
of the MCP402X Non-Volatile Digital
Potentiometer. A 6 pin PIC10F206-I/OT
with FLASH memory is utilized to generate all of the
Low-Voltage (LV) and High-Voltage (HV) MCP402X serial
commands when the 2 momentary switches are depressed
in various sequences. This enables the user to Increment
and Decrement the wiper, save the setting to EEPROM &
exercise the WiperLock™ feature.
Op Amps and PGAs
MCP651 Input Offset Evaluation Board
(MCP651EV-VOS)
The MCP651 Input Offset Evaluation
Board is intended to provide a simple
means to measure the MCP651 Input
Offset Evaluation Board op amp’s input
offset voltage under a variety of operating
conditions. The measured input offset voltage (Vost
includes the input offset voltage specified in the data
sheet (Vos) plus changes due to: power supply voltage
(PSRR), common mode voltage (CMRR), output voltage
(AOL), input offset voltage drift over temperature (ΔVos/
ΔTA) and 1/f noise.
