Yes A micro -power computing amplifier optimizes the single power operation under 5V and can work at 2.4V voltage.

Absorb the minimum power current in EL8186, while meeting excellent DC accuracy noise and output drive specifications. The competitive equipment seriously reduces these parameters to obtain micro -power current. The offset current, voltage and current noise, conversion rate, and gain bandwidth are 2 to 10 times better than the previous micro -power computing amplifiers.

EL8186 can be operated by one lithium battery or two nickel -cadmium batteries. The input range includes positive and negative. The output swing to two orbit. Ordering information

The MSL of Intersil's lead-free products is classified as a lead-free peak return welding temperature, which meets or exceeds the lead-free requirements of IPC/JEDEC J STD-020.

Typical performance curve

Application information [123 ] Introduction EL8186 is a rail input and output micro -power single power supply amplifier with enlightenment function. The device implements the input and output operation of the orbit to eliminate the problems caused by the traditional rail input and output computing amplifier. Input

El8186's input co -mode voltage range from negative power to positive power supply without introducing the offset error or performance of the traditional rail input computing amplifier. Many RailTo-Rail input levels use two differential input pairs, a long tail PNP (or PFET) and a NPN (or NFET). It is necessary to pay serious costs for this topology. When the input signal is moved from one power rail to another, the operation amplifier is switched from one input pair to another input pair, which causes the severe changes in the input offset voltage and the amplitude value of the input offset current and the accident of polarity and polarity Variety.

EL8186 achieved the input track pairing performance without sacrificing important accuracy specifications and not reducing distortion performance. EL8186's input offset voltage shows smooth behavior throughout the input range of the co -mode. EL8186's input bias current provides consistent behaviors from 10 millivolves to normal to normal.

Input bias current compensation

The input bias current of EL8186 is reduced to a typical 500Pa, while maintaining the excellent bandwidth of the micro -power computing amplifier. EL8186 has an input bias offset circuit. The input -level transistor still has enough current to ensure speed, but the offset circuit absorbs most of the base current, leaving a small part as the input bias current. Input bias current compensation/elimination usually runs from 10mv at the top of the negative to the positive power rail.

The output of the rail

A pair of complementary MOSFET devices realize the rail ring output swing. NMOS absorbing current makes the output swing in the negative direction. PMO provides a current output to swing in the front direction. EL8186 with a load of 100k will swing in the 3mv range of the power rail.

Enable/disable function

EL8186 provides an EN-PIN. Low activation pins are disabled at least 2.2V. When disabled, this part is usually consumed by 3 μA, and the output is in a high impedance state. EN also has an internal pull -down. If you keep it open, the EN pin will be pulled to the negative, and the device will be opened by default. During the disable, the high impedance of the output end allows multiple EL8186s as a MUX connection. If the output is connected together, you can select a channel through the EN pin.

Typical application

The thermocouple is the most popular temperature sensing equipment. Because of its low cost, strong interchangeability, it can be measured to measureA wide range of temperature.EL8186 is used to convert the voltage of differential thermal power puppets to a single -end signal with a gain of 10 times.EL8186's rail -to -orbit input characteristics allow the thermocouple to bias on the ground, and the converter runs from a 5V power supply.
