Applications
The MCP4726A2T-E/CH is used in precision analog output applications such as programmable voltage references, sensor excitation sources, and AGC control loops where a microcontroller must generate an accurate analog set-point via I2C. Its non-volatile EEPROM ensures that the last programmed output voltage is automatically restored after power cycling, making it ideal for battery-operated instruments and calibration modules that must maintain calibration without host communication on startup. The tiny SOT-23-6 footprint minimizes board area in wearable devices, handheld meters, and compact IoT nodes.

Frequently Asked Questions
What resolution does the MCP4726A2T-E/CH DAC provide and how accurate is the output step size?
The MCP4726A2T-E/CH is a 12-bit DAC, providing 4096 discrete output levels across the full-scale voltage range. With a 3.3 V reference, this gives an LSB step of approximately 0.8 mV, enabling fine analog voltage control suitable for precision sensor biasing, servo positioning, and calibration applications requiring sub-millivolt resolution.
How does the MCP4726A2T-E/CH retain its output setting after power loss?
The MCP4726A2T-E/CH includes integrated non-volatile EEPROM that stores the programmed 12-bit DAC output code. When power is restored, the device automatically loads the saved value and begins driving the stored analog output within a few milliseconds, eliminating the need for the host microcontroller to re-send calibration data on every boot cycle.
Which supply voltage does the MCP4726A2T-E/CH operate from, and is it compatible with 3.3 V systems?
The MCP4726A2T-E/CH operates from a supply voltage of 2.7 V to 5.5 V, making it directly compatible with both 3.3 V and 5 V microcontroller systems. The analog output is referenced to VDD, so a stable and accurate supply is important; a low-dropout regulator with 10 µF output capacitance is recommended when high DAC accuracy is required.
For a compact motor-control or sensor system, how little PCB space does the MCP4726A2T-E/CH require?
The MCP4726A2T-E/CH is packaged in a 6-pin SOT-23 form factor, measuring approximately 2.9 mm × 1.6 mm, which is one of the smallest surface-mount DAC footprints available. Only 3 external connections beyond power and ground are needed (SDA, SCL, and output), allowing it to fit into densely populated boards or even single-layer flex circuits in wearable applications.
