8/10/12-bit Digital-to-Analog Converters with I²C/SPI Interface

The MCP47CXBXX / MCP48CXBXX are single and dual-channel 8-bit, 10-bit and 12-bit buffered voltage output Digital-to-Analog Converters (DAC), with volatile or MTP memory and an I2C/SPI interface. The MTP memory can be written by the user up to 32 times, for each specific register. The nonvolatile memory includes power-up output values, device configuration registers and general purpose memory.



FEATURES

  • I2C and SPI interface

  • Single and dual channel

  • 5V capable

  • 16 μs settling time

  • Wide resolution range: 8-bit, 10-bit and 12-bit

  • Volatile and Nonvolatile Memory (MTP)

  • 1 LSB Integral Nonlinearity (INL) error

  • Voltage reference source options: Vdd, EXT, INT

  • Power-on/Brown-out Reset (POR/BOR) protection

  • Extended temperature range: –40°C to +125°C

  • Packages: lead and no-lead packaging: QFN-16, DFN-10 and MSOP-10


APPLICATIONS

  • Set point or offset trimming

  • Sensor calibration (cameras, thermostat)

  • Low-power portable instrumentation (smart devices, headsets)

  • PC peripherals

  • Data acquisition systems (automotive, industrial applications)


BENEFITS

  • Integrated memory options eliminate the need for any additional memory for design

  • Wide resolution range (8-, 10- and 12-bit) allows for flexible design

  • Internal output buffer helps reduce cost and size of external buffers
