Maxim Integrated's MAX6161AESA Voltage Reference

The MAX6161AESA from Maxim Integrated is a precision, low-dropout, micropower voltage reference in a compact 8-pin NSOIC package. This high-stability device is designed to deliver a fixed voltage output of 5V with exceptional accuracy and temperature stability, making it an ideal choice for precision voltage regulation in a wide array of applications.

One of the standout features of the MAX6161AESA is its low dropout voltage, which ensures reliable performance even when the supply voltage is close to the output voltage. This characteristic makes it particularly useful for battery-operated devices where power efficiency is critical. Additionally, the device boasts a low supply current of typically 180µA, further enhancing its suitability for portable and low-power applications.

The MAX6161AESA provides an initial accuracy of ±0.2% and a temperature coefficient of just 20ppm/°C (max), ensuring that the output voltage remains consistent across a wide temperature range from -40°C to +85°C. Such precision guarantees stable and reliable operation in systems where voltage accuracy is paramount, such as data conversion, industrial controls, and precision instruments.

Moreover, the device features a trimmable output, which allows users to fine-tune the output voltage to their specific requirements via external resistors. This flexibility is beneficial for designers who need to calibrate or compensate for system variations during manufacturing or in the field.

For enhanced system reliability, the MAX6161AESA includes a force-sense configuration that corrects for any voltage drops due to the resistance of the PCB traces, ensuring the voltage at the load is accurately regulated. It also offers excellent transient response, which is critical in applications that experience rapid changes in load.

In summary, the MAX6161AESA is a robust, high-precision voltage reference from Maxim Integrated that offers excellent temperature stability, low dropout, and low power consumption, packaged in a space-saving 8-pin NSOIC. Its versatility and reliability make it an ideal solution for designers looking to maintain voltage accuracy in their electronic systems.
