Description
Multi function pin: When Serial mode is enabled, a logic low on this pin selects Channel A. In Parallel
mode, this bit 3 for the gain control interface.
Bit 4 for channel A parallel gain control interface.
Bit 5, (MSB) for channel A parallel gain control interface.
MSB for the mode control parallel, SPI, up/down interface.
LSB for the mode control parallel, SPI, up/down interface.
A logic low on this pin enables high performance mode. A logic high enables nominal performance
mode.
Ground
Multi function pin: When CSA or CSB is pulled low, SDIO is used for reading and writing to the SPI port. In
parallel mode, This bit is 5 (MSB) for the channel B parallel gain control interface.
Multi function pin: When SPI mode is selected this pin is the serial clock input. In parallel mode this pin is
bit 4 for channel B gain interface.
Multi function pin: When the UP/DOWN mode is enabled, this pin is the MSB for the gain step size control.
When serial mode is enabled, a logic low on this pin selects channel B. In parallel mode, this is bit 3 of the
gain control interface.
Multi function pin: When the UP/DOWN mode is enabled, this pin is the LSB for the gain step size control.
A logic high enables the channel B SPI port fast attack mode. In parallel mode this pin is bit 2 for channel
B gain interface.
Multi function pin: this pin is the clock interface for channel B UPDN function. In Parallel mode this pin is
bit1 for channel B gain interface.
Multi function pin: this pin is the data pin for channel B UPDN function. In parallel mode this is bit 0 for
channel B gain interface.
Latch, a low input results in gain change. A high input results in no gain change.
Channel B negative input.
Channel B positive input.
