Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic Description 1 –DSX1 Channel 1 Negative Signal Input to DSX1. 2 +DSX1 Channel 1 Positive Signal Input to DSX1. 3 PAO1 Channel 1 Preamplifier Output. 4 FBK1 Channel 1 Preamplifier Feedback Pin. 5 PAI1 Channel 1 Preamplifier Positive Input. 6 COM1 Channel 1 Signal Ground. When this pin is connected to positive supply, Preamplifier 1 shuts down. 7 COM2 Channel 2 Signal Ground. When this pin is connected to positive supply, Preamplifier 2 shuts down. 8 PAI2 Channel 2 Preamplifier Positive Input. 9 FBK2 Channel 2 Preamplifier Feedback Pin. 10 PAO2 Channel 2 Preamplifier Output. 11 +DSX2 Channel 2 Positive Signal Input to DSX2. 12 –DSX2 Channel 2 Negative Signal Input to DSX2. 13 VGN2 Channel 2 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive voltage increases gain. 14 VOCM Input to this pin defines the common mode of the output at OUT1 and OUT2. 15 OUT2 Channel 2 Signal Output. 16 GND2 Ground. 17 VPOS Positive Supply. 18 VNEG Negative Supply. 19 VNEG Negative Supply. 20 VPOS Positive Supply. 21 GND1 Ground. 22 OUT1 Channel 1 Signal Output. 23 VREF Input to this pin sets gain scaling for both channels to 2.5 V = 20 dB/V and 1.67 V = 30 dB/V. 24 VGN1 Channel 1 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive voltage increases gain. |
