Chapter 1. Product Overview
1.1 INTRODUCTION
This chapter provides an overview of the 1LSb Octal DAC Evaluation Board.
The MCP47CXBX8/MCP48CXBX8 is a 12-bit, 1 LSb DAC. The devices offer two mem-
ory options: MCP47CVBX8/MCP48CVBX8 devices have volatile memory, while the
MCP47CMBX8/MCP47CMBX8 have 32-times programmable nonvolatile memory
(MTP).The devices operate from a single supply voltage of 2.7V to 5.5V for full
specified operation and 1.8V to 5.5V for digital operation.
The devices populated on the 1LSb Octal DAC Evaluation Board are the nonvolatile
I
2
C DAC (MCP47CMB28) and the nonvolatile SPI DAC (MCP48CMB28).
1.2 1LSb OCTAL DAC EVALUATION BOARD OVERVIEW
The Microchip 1LSb Octal DAC Evaluation Board is used to evaluate the MCP47CX-
BX8 and MCP48CXBX8 DAC families. Users can now easily evaluate features of the
MCP47CXBX8/MCP48CXBX8 devices by connecting the evaluation board to any of
the Microchip Curiosity microcontroller development boards. The 1LSb Octal DAC
Evaluation Board supports the mikroBUS™ click™ board and can be mounted on any
of the mikroBUS supported MCU boards. The 1LSb Octal DAC Evaluation Board sup-
ports both the I
2
C family (MCP47CXBX8) of devices and the SPI DAC family
(MCP48CXBX8).
