ADR550BRTZ-REEL7

ADR550BRTZ-REEL7 is a precision voltage reference from Analog Devices Inc., specialized for industrial and consumer electronic applications. It is categorized as a PMIC--voltage reference, which is designed to control and monitor voltage levels between 2.5V and 18V. This integrated circuit is designed to operate with a low-current of only 1 μA (typical) and low-dropout of 400mV. It offers high accuracy with up to ±0.2% maximum reference voltage accuracy over temperature and line.

The main application fields of the ADR550BRTZ-REEL7 are digital power supplies and general-purpose voltage references. It can be used as a main reference, or with post-regulation tracking to improve voltage accuracy. It is also typically used in systems that require multiple, low-power references such as benchtop supplies, programmable logic controllers, and MCU-based applications.

The device features low-power operation, guaranteed reference voltage accuracy over temperature and line, and a 200mV precision bandgap. This makes it suitable for applications that require low-power consumption, low-noise, and accurate voltage reference. Additionally, the device is available in an 8-lead SOIC package, which makes it suitable for use in space-constrained applications.

The ADR550BRTZ-REEL7 utilizes a bandgap reference internally. This bandgap is created using two sets of opposing diode-connected transistors with different bandgap voltages. This creates a voltage difference between the two transistors, which is the reference voltage. A voltage follower then buffers this reference voltage and drives the output. The reference output is then trimmed by the internal circuitry to achieve high accuracy.

The ADR550BRTZ-REEL7 offers a high accuracy reference voltage over temperature and line, low-power operation, and small package size, making it a suitable choice for many applications in industrial and consumer areas. It is a reliable and cost-effective option for applications requiring precision voltage references.
