Microchip MCP47A1 6-bit Volatile DAC

Microchip MCP47A1 6-bit Volatile Digital-to-Analog Converter (DAC) is a low-power, low-cost device featuring a 1.8-5.5V wide operating voltage range. Microchip MCP47A1 is ideal for applications in the automotive, audio and industrial markets, such as portable, handheld battery-operated products, and applications such as set-point or offset trimming and sensitive mechanical-trim pot replacement. The extended temperature range of -40 to +125ºC allows for use in high-temperature automotive and industrial applications. The small SC70 packaging allows for more portable and space-constrained consumer applications. MCP47A1 DAC also provides 65 taps through an I²C interface. This includes taps to both full-scale and zero-scale, providing additional functionality. The low power consumption of MCP47A1 extends lifetimes in applications with finite power supplies.

Microchip MCP4728 Quad 12-bit DACs

The Microchip Technology MCP4728 is the industry's first 12-bit Quad Digital-to-Analog Converter (DAC) to include non-volatile EEPROM, which allows the DAC's configuration to be loaded automatically on start up. The non-volatile EEPROM gives designers the flexibility to program MCP4728 DAC input codes, configuration bits, and I²C address bits to the EEPROM using I²C serial-interface commands. This Microchip Technology Quad DAC holds its data during power-off time and its configuration and outputs are available immediately after power-up. The Microchip Technology MCP4728 also extends battery life by allowing each channel to be individually shut down, which can reduce power consumption to as low as 0.04 microamperes.


Features
  • 12-Bit Resolution
  • 4 Buffered Voltage Outputs
  • Single-Supply Operation: 2.7V to 5.5V
  • On-Board Non-Volatile Memory (EEPROM)
  • Normal or Power-Down Mode
  • Internal or External Voltage Reference Selection
  • Rail-to-Rail Output
  • Low Power Consumption
  • ±0.2 LSB DNL (typical)
  • I2C Interface
    • Address bits: User Programmable to EEPROM
