Frequently Asked Questions
How many output voltage levels can the MCP4725A1T-E/CH produce, and what is the maximum output voltage?
The MCP4725A1T-E/CH is a 12-bit DAC, providing 4096 discrete output levels. With a maximum analog output voltage of 5.5 V, each LSB step represents approximately 1.34 mV, enabling very fine-grained analog voltage control for precision instrumentation and calibration tasks.
Does the MCP4725A1T-E/CH retain its programmed value after power is removed?
Yes, the MCP4725A1T-E/CH includes an integrated non-volatile EEPROM that stores the DAC output setting. After a power cycle, the device automatically restores its last programmed 12-bit value, eliminating the need for a host microcontroller to re-initialize the output on every startup.
Which interface protocol does the MCP4725A1T-E/CH use, and how many devices can share a bus?
The device communicates over the I2C serial bus. Address pins allow multiple MCP4725 devices to share a single 2-wire I2C bus, supporting standard 100 kHz and fast-mode 400 kHz data rates, which suits daisy-chained multi-channel DAC designs in a wide range of embedded systems.
Is the SOT-23-6 package of the MCP4725A1T-E/CH suitable for small PCB designs?
The SOT-23-6 package measures approximately 2.9 mm × 1.6 mm, making it one of the smallest footprints available for a 12-bit DAC with non-volatile memory. This compact size is well suited for wearable devices, battery-powered sensors, and any PCB where board area is at a premium.
