MCP48CVB04-20E/ST

Digital To Analog Converters Overview

The MCP48CVB04-20E/ST is a quad-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and an SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It offers reference source options including VDD, external VREF, or an internal band gap (1.214V typical). Integral Nonlinearity (INL) is specified at ±1 LSB. The component is housed in a 20-lead TSSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure that the selected variant matches the required memory configuration, as this model utilizes volatile RAM rather than nonvolatile MTP. Cross-reference the datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with buffered outputs is required. The volatile memory characteristic necessitates re-initialization upon power-up if state retention is needed. Consider the internal band gap option if an external reference voltage source is unavailable. Verify that the system logic levels are compatible with the SPI interface requirements across the intended operating voltage range.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXBX4/8 family, which includes both volatile (CVB) and nonvolatile (CMB) memory variants. The '04' designation indicates a quad-channel configuration with 8-bit resolution. Other family members offer different resolutions (10-bit, 12-bit) or octal channel counts. The CVB series specifically relies on volatile RAM for DAC register storage.
