Maxim Integrated MAX6192CESA Voltage Reference IC
The MAX6192CESA from Maxim Integrated is a precision voltage reference IC designed to provide a stable and accurate reference voltage for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision circuit applications. This device is part of Maxim's family of low-noise, high-precision voltage references that cater to a wide array of electronic systems requiring high stability and low drift over time and temperature.
Encased in an 8-pin NSOIC package, the MAX6192CESA offers a series reference with a fixed output voltage of 4.096V, which is a common reference level for 12-bit or 16-bit converters operating on a 5V supply. The output voltage is laser-trimmed to a high accuracy of ±0.02% (max) at room temperature. Moreover, the device boasts an impressive temperature coefficient of typically 3ppm/°C, ensuring minimal deviation across the operating temperature range from -40°C to +85°C.
One of the key features of the MAX6192CESA is its low dropout voltage, making it suitable for applications with a tight power supply headroom. Additionally, its low supply current of typically 160µA (max 180µA) makes it an excellent choice for power-sensitive designs. The device also has a high output current capability of up to 15mA, which is beneficial for driving heavy loads or buffering for ADCs/DACs.
The IC is designed with a force-sense configuration, which helps to minimize errors due to PCB trace resistance, ensuring that the reference voltage at the load is as accurate as possible. Furthermore, the MAX6192CESA includes a shutdown feature that reduces supply current to 1µA (max), providing an additional power-saving mode for battery-operated devices.
Maxim Integrated's MAX6192CESA is an ideal voltage reference source for precision data converters, portable instrumentation, and industrial control systems, among other applications. Its combination of high precision, stability, and low power consumption makes it a reliable component for maintaining the integrity of analog signals in complex electronic systems.
