One COM amplifier is able to deliver high output current, up to ±150mA.
Amplifiers A and B feature positive single supply inputs for common mode voltage, thus can be used for the highest gamma voltages.
The amplifiers C to T inclusive, and the COM amplifier, feature negative single supply inputs and are dedicated to the lowest gamma voltages.
The TSL1020 is fully characterized and guaranteed over a wide industrial temperature range (-40 to +95°C).
