MCP48CMB18T-20E/ST

Overview

The MCP48CMB18T-20E/ST is an octal-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features Multi-Time Programmable (MTP) nonvolatile memory for retaining configuration and output values across power cycles. The device operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. It utilizes a 4-wire SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The component is housed in a 20-lead TSSOP package and is rated for an extended operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates MTP nonvolatile memory allowing user programming of up to 32 locations per register using a high-voltage HVC pin.

Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel packaging details. Ensure that the required high-voltage level on the LAT/HVC pin is supported by the system design for successful MTP programming operations.

Selection Notes

Select this component when an octal channel count is required alongside nonvolatile data retention capabilities. Consider the 10-bit resolution and buffered voltage outputs for applications needing precise analog signal generation controlled via a standard SPI interface.

Part Context

This part belongs to the MCP48CXBX4/8 family, which includes quad and octal variants with 8-bit, 10-bit, and 12-bit resolutions. The 'M' designation indicates the inclusion of MTP nonvolatile memory, distinguishing it from volatile RAM-based counterparts within the same series.
