AD780BRZ

The AD780BRZ is an ultra-high precision bandgap reference voltage chip designed for a wide range of high-performance applications. This chip offers several key features and benefits that make it an ideal choice for many precision reference voltage source applications.

Key Features:

1. Programmable Output Voltage: The AD780BRZ provides a pin-programmable 2.5V or 3.0V output from a 4V to 36V input range. This flexibility allows it to be used in various applications with different voltage requirements.
2. High Precision and Low Drift: With a maximum variation of 0.9mV over the operating temperature range of -40°C to +85°C, the AD780BRZ offers high precision and low temperature drift. This ensures stable and accurate voltage reference over a wide range of operating conditions.
3. Low Noise: The AD780BRZ features extremely low noise, typically 4mV peak-to-peak from 0.1Hz to 10Hz, and a wideband spectral noise density of 100nV/√Hz. This low noise performance is critical for many high-resolution analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) where noise can degrade the signal-to-noise ratio (SNR).
4. Low Static Current and Output Trim Capability: The AD780BRZ operates with a low static current of up to 1mA, making it suitable for low-power applications. Additionally, it offers an optional fine-trim connection for applications that require even higher accuracy.
5. Temperature Output Pin: The AD780BRZ includes a temperature output pin that provides an output voltage that varies linearly with temperature. This feature allows the chip to be configured as a temperature transducer while providing a stable 2.5V or 3.0V reference output.
6. Package Options: The AD780BRZ is available in PDIP and SOIC packages, providing flexibility in terms of board layout and design.

Applications:

The AD780BRZ is suitable for a wide range of high-performance reference applications, including high-resolution ADCs and DACs, precision measurement and control systems, and any other application where a stable and accurate voltage reference is required.

In summary, the AD780BRZ is an ultra-high precision bandgap reference voltage chip that offers high precision, low drift, low noise, low static current, and a temperature output pin. Its versatile features and performance make it an ideal choice for many high-performance reference applications.
