The AD9083 is a 16-channel, 125 MHz bandwidth, continuous time ?-? (CTSD) ADC. The device features an on-chip, programmable, single-pole antialiasing filter and termination resistor that is designed for low power, small size, and ease of use. The 16 ADC cores features a first-order, CTSD modulator architecture with integrated, background nonlinearity correction logic and self cancelling dither. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.

The ADN8833 is a monolithic H-bridge TEC driver with integrat-ed 1 A power MOSFETs. It has a linear power stage with the linear driver (LDR) output and a pulse-width modulation (PWM) power stage with the SW output. Depending on the control voltage at the CONT input, the ADN8833 drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature.The control voltage applied to the CONT input is generated by a digital-to-analog converter (DAC) closing the digital proportional, integral, derivative (PID) loop of temperature control system.The internal 2.5 V reference voltage provides a 1% accurate output that is used to bias a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes.
