Integrated Circuits (ICs)

The NJ88C33 is a synthesiser circuit fabricated on Mitel Semiconductor's 1.4 micron CMOS process, assuring very high performance. It is I2C compatible and can also be programmed at up to 5MHz. It contains a 16-bit R counter, a 12-bit N counter and a 7-bit A counter. A digital phase comparator gives improved loop stability with current source outputs to reduce loop components. A voltage doubler is provided for the loop driver to improve control voltage range to the VCO when operating at low supply voltages.

General Purpose Amplifier 2 Circuit 8-PDIP

The NE5532P are high-performance operational amplifiers combining excellent dc and ac characteristics. They feature very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, high slew rate, input-protection diodes, and output short-circuit protection. These operational amplifiers are compensated internally for unity-gain operation. These devices have specified maximum limits for equivalent input noise voltage.

Specification:

The MC3374 is perfect for narrowband audio and data applications up to 75 MHz which require extremely low power consumption. Battery-powered applications down to VCC = 1.1 V are possible. The MC3374 also includes an onboard voltage regulator, low battery detection circuitry, a receiver enable allowing a power down Sleep–Mode, two undedicated buffer amplifiers to allow simultaneous audio and data reception, and a comparator for enhancing FSK (Frequency Shift Keyed) data reception to 1200 baud.
