The KSC838 OTA is a high performance, low power, CMOS operational transconductance amplifier (OTA) which features large differential gains over a very broad temperature range, with integrated temperature compensation. It requires no external components to achieve an amplifier gain of 20kHz without loading or boosting the signal. The integrated voltage compensation provides an ideal load regulation and superior ripple rejection, allowing signal amplification over a range of frequency components that are impossible to achieve using conventional OTA designs. Together these attributes make the KSC838 OTA an excellent choice for building signal amplification applications.

In the field of signal amplification, the KSC838 OTA is commonly used for a variety of operational and analog circuits, such as operational amplifiers, voltage-controlled oscillators, active filters, integrators, sample-and-hold circuits, signal inverters, modulators, analog multipliers, and many more. Its ability to maintain high gain and large input dynamic range makes it a good choice for applications that require wide output swing, high gains, and low pass common mode rejection. Additionally, the KSC838 OTA can be used in a variety of high-speed data converter designs that require a large signal source current and high accuracy.

The KSC838 OTA can be used in a single or dual channel configuration, providing two outputs with adjustable gains. The OTA is an integral part of the analog signal chain, and its accuracy and performance is paramount. The KSC838 OTA is designed to offer a wide bandwidth and high input resistance, while simultaneously providing precision and stability over temperature and supply voltage variations. In addition, the OTA incorporates two stage circuit architecture, allowing independent control of the load-line and loop gain. This design feature provides superior response time and stability over time, temperature and voltage variations, making it well-suited for many different applications.

At the core of the KSC838 OTA is an active feedback architecture. This allows the amplifier to track and respond to the changing feedback signals at ultra-high speed and maintain the output voltage within a tolerance band, even under challenging conditions. The active feedback architecture works by sensing the output node and providing a corrective response applied to the input node. By doing so, the OTA can accurately nullify any deviation from the desired voltage. This eliminates any noise or distortion caused by input-to-output translational errors, resulting in a high quality, low distortion operation. The feedback loop provides superb accuracy over all environmental conditions, which makes the amplifier suitable for use in a number of precision applications.

In addition to all these features, the KSC838 OTA also comes with a built-in MOSFET thermal resistor protection. This allows reliable operation over temperature extremes and provides an added layer of protection for the amplifier. This feature is particularly important for applications which require the amplifier to be operated under extended temperature conditions.

The KSC838 OTA is an excellent choice for all types of analog and RF circuits, due to its excellent performance, low power consumption and wide temperature range. It also provides accurate, stable, low distortion and low noise operation, as well as excellent input and output range flexibility. For these reasons, the KSC838 OTA is an ideal choice for building signal amplification applications.
