Output Amplifier
The output amplifier stage is user-programmable for gain and offset level. Gain and offset are controlled by 4-bit wide words. Gain
settings are on an exponential scale. Offset is controlled by a 4-bit wide DAC, which selects the offset voltage between 2 reference
voltages (Vhigh_dac and Vlow_dac) on a linear scale.
The offset setting is independent of the gain setting.
The gain setting is independent of amplifier bandwidth.
The amplifier is designed to match the specifications like the output of the imager array. This signal has a data rate Of 10 MHz and is
located between 1.2 and 2.4V.
Table 3. Summary of Output Amplifier Specifications
The range of the output stage input is between 1 and 4V. A lowest gain the sensor outputs a signal in between 1.2 and 2.2V, which
fits into the input range of the amplifier. The range of the output signal is between 1 and 4.5V, dependent on the gain and offset settings
of the amplifier. This range should fit to the input range of the ADC, external or internal. The on-chip ADC range is between 2 and
4V. A minimal gain setting of "3" seems necessary for the internal ADC, and the offset voltage should be set to the low-reference
voltage of the ADC.
