Overview
The UA776 from SGS-THOMSON Microelectronics is a low power, programmable single operational amplifier known for its versatility in high-accuracy, low power consumption analog applications. It operates without the need for frequency compensation, offers a broad programmable range, features a high slew rate, and includes short-circuit protection.
Key Features
MicroPower Operation: Designed for efficient power usage, the UA776 is suitable for battery-operated devices or any application where power efficiency is crucial.
Programmability: Users can optimize the amplifier’s characteristics such as input noise voltage and current, power consumption, and input current by adjusting a single resistor or current source. This functionality allows for fine-tuning the quiescent current to meet specific application needs, ranging from nano-watt power consumption to features akin to the UA741.
No External Frequency Compensation Required: This simplifies the circuit design as no additional components are needed for frequency stabilization.
High Slew Rate: Ensures rapid changes in output can be achieved, making the UA776 suitable for fast signal processing applications.
Short-Circuit Protection: The built-in short-circuit protection increases the reliability and longevity of the amplifier by preventing damage due to accidental shorting.
Applications
The amplifier’s feature set makes it ideal for use in long-time integrators, active filters, sample and hold circuits, and other analog systems where high accuracy and low power consumption are crucial.
Packaging and Temperature Ranges
The UA776 is available in different package types including DIP8 (Dual Inline Package) and SO8 (Small Outline Package), which cater to various mounting preferences. It also has a variety of part numbers corresponding to different temperature ranges:
- UA776C: 0°C to +70°C
