General description
The NE1617A is an accurate two-channel temperature monitor. It measures the temperature of itself and the temperature of a remote sensor. The remote sensor is a diode connected transistor. This can be in the form of either a discrete NPN/PNP, such as the 2N3904/2N3906, or a diode connected PNP built into another die, such as is done on some Intel microprocessors.
The temperature of both the remote and local sensors is stored in a register that can be read via a 2-wire SMBus. The temperatures are updated at a rate that is programmable via the SMBus (the average supply current is dependent upon the update rate—the faster the rate, the higher the current).
In addition to the normal operation, which is to update the temperature at the programmed rate, there is a one-shot mode that will force a temperature update.
There is also an alarm that senses either an overtemperature or undertemperature condition. The trip points for this alarm are also programmable.
The device can have 1 of 9 addresses (determined by 2 address pins), so there can be up to 9 of the NE1617A on the SMBus.
can also be put in standby mode (in order to save power). This can be done either with software (over the SMBus) or with hardware (using the STBY pin).

General description
The TFA9812 is a high-efficiency Bridge Tied Load (BTL) stereo Class-D audio amplifier with a digital I2S audio input. It is available in a HVQFN48 package with exposed die paddle. The exposed die paddle technology enhances the thermal and electrical performances of the device.
The TFA9812 features digital sound processing and audio power amplification. It supports I2C control mode and Legacy mode. In Legacy mode I2C involvement is not needed because the key features are controlled by hardware pin connections.
A continuous time output power of 2 ´ 12 W (RL = 8 W, VDDP = 15 V) is supported without an external heat sink. Due to the implementation of a programmable thermal foldback even for high supply voltages, higher ambient temperatures, and/or lower load impedances, the device operates without sound interrupting behavior.
TFA9812 is designed in such a way that it starts up easily (no special power-up sequence required). It features various soft and hard impact protection mechanisms to ensure an application that is both user friendly and robust.
A modulation technique is applied for the TFA9812, which supports common mode choke approach (1 common mode choke only per BTL amplifier stage). This minimizes the number of external components.

The HEF4020B is a 14-stage binary counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (Q0, and Q3 to Q13). The counter advances on the HIGH to LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. A feature of the device is its high speed (typ. 35 MHz at VDD = 15 V).
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the full industrial (-40 °C to +85 °C) temperature range.

*High speed operation
*Fully static operation
*5 V, 10 V, and 15 V parametric ratings
*Standardized symmetrical output characteristics
*Operates across the full industrial temperature range -40 °C to +85 °C
*Complies with JEDEC standard JESD 13-B
*ESD protection:
-HBM JESD22-A114E exceeds 2000 V
-MM JESD22-A115-A exceeds 200 V

The NE/SA612A is a low-power VHF monolithic double-balanced mixer with on-board oscillator and voltage regulator. It is intended for low cost, low power communication systems with signal frequencies to 500MHz and local oscillator frequencies as high as 200MHz. The mixer is a “Gilbert cell” multiplier configuration which provides gain of 14dB or more at 45MHz.
The oscillator can be configured for a crystal, a tuned tank operation, or as a buffer for an external L.O. Noise figure at 45MHz is typically below 6dB and makes the device well suited for high performance cordless phone/cellular radio. The low power consumption makes the NE/SA612A excellent for battery operated equipment. Networking and other communications products can benefit from very low radiated energy levels within systems. The NE/SA612A is available in an 8-lead dual in-line plastic package and an 8-lead SO (surface mounted miniature package).

*Low current consumption
*Low cost
*Operation to 500MHz
