The SP490ES-L is an integrated circuit designed for unbalanced applications. It is a low-voltage powered receiver and transmitter designed for use in automotive and remote control systems that require reliable operation in the presence of high electromagnetic interference. The receiver has a relatively high sensitivity, wide frequency range, and low operating current. The low-voltage operation enables the circuit to be used in automobiles and other power-starved applications.

The SP490ES-L is a transceiver circuit that can be used for both transmitting and receiving. The circuit is powered by a single 3V supply. The transmitter section consists of two differential amplifiers, one for the current source and the other for the voltage reference input. Both amplifiers have offset compensation circuitry which ensures a precise output signal level. The receiver is designed to accurately accept an input signal over a wide range of frequencies and to provide an output with a very low noise floor.

The SP490ES-L is a unbalanced transceiver circuit with two independent pins for the data inputs and two independent pins for the data outputs. The circuit is designed to interface with a variety of unbalanced interfaces like frequency-modulated systems. The outputs are 3V CMOS compatible with a wide operating temperature range. The transmitter section consists of a differential amplifier for the input data, a current source for the reference input, and a voltage amplifier for the output. An offset compensation circuit is also included.

The SP490ES-L is intended for use as a low-cost and low-power transceiver. It is well suited for applications such as remote controls, telemetry, and automotive systems. The SP490ES-L has an integrated CMOS driver that is designed to work with low-voltage MPU configurations such as 5V communication lines. The integrated CMOS driver is designed to interface with the most commonly used low-voltage communication circuits such as CMOS logic and TTL. The receiver section consists of a variable gain amplifier and a voltage amplifier. The variable gain amplifier is intended to match the performance of the transmitter section, while the voltage amplifier is designed to provide a low noise, high sensitivity output.

The SP490ES-L is a versatile transceiver that is designed to work in the most demanding applications. Its low-power design, wide frequency range, and good sensitivity make it a good choice for both remote control and automotive systems. The integrated CMOS driver makes it an excellent choice for designs requiring low-voltage operation. The receiver section is highly sensitive and provides a low-noise output with wide frequency response. Due to its low-voltage design and its ability to interface with many unbalanced systems, the SP490ES-L is an ideal choice for applications requiring reliable communication and low power consumption.
