VRE305KD

The VRE305KD is a precision voltage reference IC that operates from 1.25V to 5.5V with a temperature drift as low as 10ppm/°C. It is designed for a wide range of applications including datacom, consumer and automotive systems. The device is available in an 8-pin SOIC package with an extended operating temperature range of -40°C to +150°C.

The VRE305KD employs innovative design techniques to eliminate the need for external components. This includes an internal comparator for fault detection and hysteresis for stability. Also, a Silicon Temperature Sensor (STS) is integrated to improve accuracy and reduce temperature drift for applications requiring precision analog circuitry. The STS is optimized to reduce power consumption and provide a reliable reference voltage of 2.5V.

The VRE305KD features a wide input voltage range of 1.25V to 5.50V and a low temperature drift (typical of 10 ppm/degree C). This makes the device ideal for high voltage systems such as automotive and medical. High performance is attained by leveraging advanced design techniques such as low offset, low temperature drift and low output impedance. The internal comparator has a fault detection threshold of ±3mV and the hysteresis of the voltage reference is adjustable for improved stability.

The VRE305KD is suitable for use in precision analog systems such as data conversion, signal conditioning and audio systems. The device features an integrated 6-bit DAC which provides a 15mV full scale output range. This wide range provides flexibility and is ideal for both low and high precision applications. The integrated DAC allows easy adjustment of the output voltage and is compatible with microprocessor and microcontroller systems.

The VRE305KD incorporates an internal temperature sensor and provides an accurate temperature compensation of the reference voltage over the full operating temperature range. This ensures temperature stability and improves in precision. The voltage reference also offers improved power supply rejection and better line regulation. In addition, the device provides a disable pin which allows both the DAC and temperature sensor functions to be disabled, thus conserving power.
