Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic Description 1, 191 VMDO VMID Buffer Output. Requires robust ac decoupling with a capacitance of 0.1 μF capacitor or greater. 2 TXEN Driver Enable. Logic threshold = 1.1 V with ±0.2 V hysteresis. 3 VMDI VMID Input Voltage. Normally decoupled with a 0.1 μF capacitor. When pulled to VNCM, the VMID buffer shuts down. This can be useful when using the part with dual supplies or when an external midpoint generator is used. 4 VNCM Negative Supply for Bias Cell, VMID Cell, and Logic Inputs. (Ground this pin in applications.) 5 VPSB Positive Supply for Bias Cell and VMID Cell. 6 ENBL Enable. Logic threshold = 1.1 V. When low, the AD8260 is disabled and the supply current is 35 μA when TXEN and all GNSx pins are also low. 7 VGAP Positive VGA Output (Needs to Be Ac-Coupled for Single Supply). 8 VGAN Negative VGA Output (Needs to Be Ac-Coupled for Single Supply). 9, 161 VNGR Negative Supply for Preamplifier and DGA (Set to −VPOS for Dual Supply; GND for Single Supply). 10, 201 VPSR Positive Supply for Preamplifier, DGA, and GNSx Logic Decoder. 11 GNS3 MSB for Gain Control. Logic threshold = 1.1 V. 12 GNS2 Gain Control Bit. Logic threshold = 1.1 V. 13 GNS1 Gain Control Bit. Logic threshold = 1.1 V. 14 GNS0 LSB for Gain Control. Logic threshold = 1.1 V. 15 PRAO Preamplifier Output. 17 FDBK Negative Input of Preamplifier. 18 PRAI Positive Input of Preamplifier. 21, 221 VPOS Positive Supply for Driver Amplifier. 23, 241 TXOP Driver Output. 25, 261 VNEG Negative Supply for Driver Amplifier (Set to −VPOS for Dual Supply; GND for Single Supply). 27 TXFB Feedback for Driver Amplifier. 28 INPN Negative Driver Amplifier Input. 29 INRN Negative Gain Resistor Input for Driver Amplifier. 30 INRP Positive Gain Resistor Input for Driver Amplifier. 31 INPP Positive Driver Amplifier Input. 32 VOCM Output Common Mode Pin. Normally connected to Pin VMDO. 1 Pins with the same name are connected internally. |
