ADN8834ACPZ-R2 Dettagli del prodotto

Analog Devices ADN8834ACPZ-R2 Ultra-compact 1.5A Thermoelectric Cooler (TEC) Controller consists of a linear power stage, a pulse-width modulation (PWM) power stage, and two zero-drift, rail-to-rail operational amplifiers. The ADN8834ACPZ-R2 controller controls and delivers bidirectional current through the TEC using two pairs of the complementary integrated MOSFETs in an H-bridge configuration. Signal conditioning is achieved by measuring the thermal sensor feedback voltage and using the integrated operational amplifiers as a proportional integral differential (PID) compensator. ADN8834ACPZ-R2 stabilizes the temperature control loop through PID compensation. The internal 2.50V reference voltage provides a 1% accurate output that is used to bias a thermistor temperature sensing bridge as well as a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. The zero drift chopper amplifiers help the ADN8834ACPZ-R2 maintain long-term temperature stability via an autonomous analog temperature control loop.
