Programmable Gain Element Using the AD5451, 10-Bit, 1CH Current Output DAC Family
Projekt referencyjny przez: Analog Devices
Programmable Gain Element Using the AD5451, 10-Bit, 1CH Current Output DAC Family. In applications where the DAC output voltage range is required to be larger than the input voltage, a programmable gain circuit can be used. This circuit provides a programmable gain function using a multiplying DAC, the AD5451 and a fast, low offset operational amplifier, the AD8065. The maximum gain value and the temperature coefficient are set by external resistors and the resolution of the programmable gain is set by the resolution of the DAC
