Amplifier performances
1) For all possible combinations of resistive load and capacitive load.
2) At DC.
3) For voltage controlled bias control. For current controlled operation the voltage drop on the
pMOS output transistor has to be less than 200mV at maximum current.
4) Short circuit protection at ~80mA.
5) This amplifier must be loaded for correct operation. Ibias is without load current.
The signal DAC is build around a programmable DAC and a buffer. It can generate fast (up to
64 kHz) or high resolution (resolution up to 16 bits) output. The output can be controlled in cur-
rent or voltage.
The amplifier can be used in several configurations. Therefore, it is not connected internally.
