DF1706E Overview
Moreover, the book has an appendix that contains a case study. There is only one mounting type recommended for the product, which is Surface Mount. There is a 28-SSOP (0.209, 5.30mm Width) case embedded in it. In this case, the device has 2 channels. There are Interpolation Filter functions included in this part for your reference. This device can be applied in both Consumer Audio, Professional Audio and X directions. As far as I know, it is supplied within 3V~3.6V days. In this device, the temperature range is -25°C~85°C TA, which is the range of this device. There are 28 terminations on the chip, which is the number of terminations on the chip. You can find similar parts by searching for the DF1706 family of parts. The following specifications are related to the device: 32kHz ~ 192kHz, which can be found here. The chip has 28 pins that are accessible from the outside. It can give voltage up to 3.3V volts. As long as the supply voltage is greater than 3.3V, it can handle it. As far as the supply current is concerned, it operates under the 45mA parameter. 24 is the total number of bits on an IC chip. Overall, this device has a total of DSP PERIPHERAL, DIGITAL FILTER uP/uC/peripheral IC types that are present.
