SL8052A

The SL8052A is a rail-to-rail dual channels operational amplifier with wide supply range from 4.5V to 16V. It provides 0.5V beyond the supply rails of common mode input range and capability of rail-to-rail output swing as well. This enables the amplifier to offer maximum dynamic range at any supply voltage among many applications. A 8MHz gain bandwidth product allows SL8052A to perform more stable than other devices in Internet applications. With features of 20V/μs high slew rate and 200ns of fast settling time, as well as 30mA (sink and source) of high output driving capability, the SL8052A is ideal for the requirements of flat panel Thin Film Transistor Liquid Crystal Displays (TFT-LCD) panel grayscale reference buffers application. Due to insensitive to power supply variation, SL8052A offers flexibility of use in multitude of applications such as battery power, portable devices and anywhere low power consumption is concerned. With standard operational amplifier pin assignment, the SL8052A is offered in a space saving 8-Pin MSOP package and specified over the -40°C to +85°C temperature range. The SL8052A rail-to-rail dual channels amplifier is built on an advanced high voltage CMOS process. It’s beyond rails input capability and full swing of output range makes itself an ideal amplifier for use in a wide range of general-purpose applications. The features of 3.2V/μS high slew rate, fast settling time, 3.5MHz of GBWP as well as high output driving capability have proven the SL8052A a good voltage reference buffer in TFT-LCD for grayscale reference applications. High phase margin and extremely low power consumption (500μA per amplifier) make the SL8052A ideal for Connected in voltage follower mode for low power high drive applications. The SL8052A can be operated with a single nominal wide supply voltage ranging from 4.5V to 18V with stable performance over operating temperatures of -40°C to +85°C. With 500mV greater than rail-to-rail input common mode voltage range and 70dB of Common Mode Rejection Ratio, the SL8052A allows a wide range sensing among many applications without having any concerns over exceeding the range and no compromise in accuracy. The output swings of the SL8052A typically extend to within 80mV of positive and negative supply rails with load currents of 5mA. The output voltage swing can be even closer to the supply rails by merely decreasing the load current. A +/−120mA short circuit current will be limited by the SL8052A if the output is directly shorted to the positive or the negative supply. For an indefinitely output short circuit, the power dissipation could easily increase such that the device may be damaged. The internal metal interconnections are well designed to prevent the output continuous current from exceeding +/−30mA such that the maximum reliability can be well maintained. The SL8052A is designed to prevent its output from being phase reversal as long as the input voltage is limited.
