MCP48FXBX4/8

Features

• Operating Voltage Range:

- 2.7V to 5.5V – Full specifications

- 1.8V to 2.7V – Reduced device specifications

• Output Voltage Resolutions:

- 8-bit: MCP48FXB0X (256 steps)

- 10-bit: MCP48FXB1X (1024 steps)

- 12-bit: MCP48FXB2X (4096 steps)

• Rail-to-Rail Output

• Fast Settling Time of 7.8 µs (Typical)

• DAC Voltage Reference Source Options:

- Device VDD

-External VREF pin (buffered or unbuffered)

- Internal band gap (1.22V typical)

• Output Gain Options:

-1x (unity)

- 2x (available when not using internal VDD as

voltage source)

• Nonvolatile Memory (EEPROM) Option:

- User-programmable Power-on Reset

(POR)/Brown-out Reset (BOR) output setting

and device Configuration bits recall

- Auto-recall of saved DAC register setting

- Auto-recall of saved device configuration

(voltage reference, gain, power-down)

• Power-on/Brown-out Reset Protection

• Power-Down Modes:

- Disconnects output buffer (high-impedance)

- Selection of VOUT pull-down resistors

(125 k

 or 1 k)

• Low-Power Consumption:

- Normal operation: <2.6 mA (quad), 3.2 mA (octal)

- Power-down operation: 680 nA typical

- EEPROM write cycle: 2.2 mA (quad),

2.7 mA (octal) maximum

• SPI Interface:

- Supports Mode 0,0 and Mode 1,1

- Up to 20 MHz writes and 10 MHz reads

- Input buffers support interfacing to

low-voltage digital devices

• Package Types: 20-Lead TSSOP,

20-Lead 5 mm x 5 mm VQFN

• Extended Temperature Range: -40°C to +125°C
