positive input.
negative input.
Mode control parallel, SPI, up/down (MSB)
Mode control parallel, SPI, up/down (LSB)
Multifunction pin: Serial data input/output (bidirectional pin) in Parallel mode, this is bit 5. (MSB)
Multifunction pin: Serial clock input. In parallel mode this bit 4.
Multifunction pin: MSB for gain step function, chip select and bit 3 in parallel operation.
Multifunction pin: LSB for gain step function, a logic high enables fast attack mode and in parallel
mode this pin is bit 2.
Multifunction pin: Clock input for up down function. In parallel mode this pin is bit 1.
Multifunction pin: Data pin for up down function. In parallel mode this is bit 0 (LSB)
Latch, a low input results in gain change. A high input results in no gain change.
Positive output.
Negative output.
Positive power supply.
Power up pin. A logic high enables the part.
High performance power mode (active high), Nominal power mode (low)
