Frequently Asked Questions
What resolution does the MCP4802-E/SN provide, and how many discrete output steps are available for DAC-controlled analog signals?
The MCP4802-E/SN is an 8-bit DAC, providing 256 discrete output steps across its analog output range up to 4.176 V maximum. Each step corresponds to approximately 16 mV per LSB, which is adequate for bias voltage control, coarse waveform generation, and programmable reference applications in embedded control systems.
Does MCP4802-E/SN support simultaneous update of both DAC output channels, and how is this achieved over SPI?
The MCP4802-E/SN provides 2 independent output channels that can be written sequentially via the SPI serial interface using channel selection bits in the command byte. The LDAC pin can be used to latch both channels simultaneously after loading them, allowing synchronous output updates useful in stereo audio and synchronized bias-voltage designs where both channels must switch at the same instant.
When is MCP4802-E/SN preferred over its 10-bit sibling MCP4812 in a cost-sensitive sensor biasing design?
The MCP4802-E/SN is chosen over the 10-bit MCP4812 when 8-bit resolution of 256 steps is sufficient for the bias voltage or reference accuracy required by the downstream circuit. For sensor bias levels where ±16 mV step size is acceptable, the MCP4802 typically carries a lower unit price and the same SOIC-8 footprint, allowing a direct pin-compatible substitution if higher resolution is later needed.
What is the typical lead time and shelf-life compliance for MCP4802-E/SN when ordering for a high-mix, low-volume production run?
The MCP4802-E/SN has a factory lead time of approximately 6 weeks and carries a JESD-609 code of e3, confirming Pb-free, RoHS-compliant moisture sensitivity rating for standard pick-and-place SMT assembly. With a YTEOL indicator of 8 years, it remains an active-lifecycle part, reducing procurement risk for low-to-medium volume production builds that require consistent availability over a multi-year product life.
