Description
Digital Positive Supply Voltage: 4.75 V to 5.25 V.
Digital Common. Connect to external circuit common using the lowest possible impedance.
Latch Enable. SPI programming pin. CMOS levels: VLOW < 0.8 V, VHIGH > 2 V.
SPI Port Clock. CMOS levels: VLOW < 0.8 V, VHIGH > 2 V.
SPI Data Input. CMOS levels: VLOW < 0.8 V, VHIGH > 2 V.
SPI Data Output. CMOS levels: VLOW < 0.8 V, VHIGH > 2 V.
Analog Common. Connect to external circuit common via a 1 kΩ resistor.
Analog Positive Supply Voltage: 4.75 V to 5.25 V.
Differential Inputs. 400 Ω input impedance. Common-mode range is 1.5 V to 2.5 V; default is 2.1 V.
Offset Correction Loop Disable. Pull high to disable the offset correction loop.
Offset Correction Loop Compensation Capacitors. Connect capacitors to circuit common.
Differential Outputs. 20 Ω output impedance. Common-mode range is 1.5 V to 3 V; default is VPS/2.
Output Common-Mode Setpoint. Defaults to VPS/2 if left open.
Analog Gain Control. 0 V to 2 V, 30 mV/dB gain scaling.
Front-End Gain Switch, 6 dB or 12 dB. Pull low for 6 dB; pull high for 12 dB.
Chip Enable. Pull high to enable.
Exposed Paddle. Connect the exposed paddle to a low impedance ground pad.
