The ADN8834ACPZ-R7 from Analog Devices is a highly integrated, ultracompact Thermoelectric Cooler (TEC) controller. It features a patented high-efficiency single inductor architecture and integrated low RDSON MOSFETs for efficient TEC control.
This device operates within a voltage range of 2.7V to 5.5V and maintains functionality across an extended temperature range of -40°C to 125°C. Key electrical specifications include a typical operating current of 3.3mA and a 2.0 MHz PWM driver switching frequency, enabling precise temperature regulation.
The ADN8834ACPZ-R7 supports both NTC thermistors and RTD thermal sensors, offering flexibility in temperature sensing. It includes two integrated, zero-drift, rail-to-rail chopper amplifiers for stable control loops and a 2.50V reference output with 1% accuracy. The controller is capable of independent TEC heating and cooling current limit settings and programmable maximum TEC voltage.
Available in a 24-lead, 4mm x 4mm LFCSP package, this TEC controller is suitable for applications requiring accurate temperature control, such as optical modules, optical fiber amplifiers, and optical networking systems. It is also AEC-Q100 qualified for automotive applications.
