Frequently Asked Questions
How many resistance steps does the MCP4652-502E/UN provide and what is its end-to-end resistance value?
The MCP4652-502E/UN provides 256 wiper steps across a 5 kΩ end-to-end resistance, giving a step size of approximately 19.5 Ω per step. This resolution is sufficient for precise gain trimming in amplifier circuits or for generating programmable voltage references with better than 0.4% adjustment granularity over the full resistance range.
Does the MCP4652-502E/UN retain its wiper position after power is removed, and how is it programmed?
Yes, the MCP4652-502E/UN stores the wiper position in on-chip non-volatile EEPROM, so it recalls the last programmed resistance at power-on without any microcontroller re-initialization. It is programmed via a standard 2-wire I2C interface at up to 400 kHz fast mode, requiring only 2 signal lines from a host MCU to set and read the 8-bit wiper register.
What supply voltage range does the MCP4652-502E/UN support for mixed 3.3 V and 5 V system designs?
The MCP4652-502E/UN operates from 2.7 V to 5.5 V, making it directly compatible with both 3.3 V microcontroller systems and legacy 5 V analog circuits. This wide range eliminates level-shifting in most mixed-signal boards and allows the digital potentiometer to sit on the same I2C bus as 3.3 V MCUs while driving 5 V analog signal-conditioning networks.
For a signal bandwidth of 2 kHz, which low-frequency control applications best match the MCP4652-502E/UN?
With a 2 kHz small-signal bandwidth, the MCP4652-502E/UN is well-matched to audio bass and treble tone control, slow programmable gain loops in sensor interfaces, and DC calibration trim circuits where adjustment rates are well below 1 kHz. It is not intended for high-frequency RF or video signal attenuation, where bandwidths of 10 MHz or more are required.
