The TMP102 device is a digital temperature sensor, which is very suitable as a replacement for NTC/PTC thermistors that require high precision. The device can provide an accuracy of ±0.5°C without calibration or without external component signal conditioning. The device temperature sensor is a highly linear product, and the temperature can be known without complicated calculations or table lookup. The on-chip 12-bit ADC has a minimum resolution of 0.0625°C.
The 1.6mm × 1.6mm SOT563 package is 68% smaller than the SOT-23 package. The TMP102 device has SMBus™, two-wire and I 2C interface compatibility, allowing up to four devices on one bus. In addition, the device also has SMBus alarm function. The rated operating voltage range of the device is 1.4V to 3.6V, and the maximum quiescent current in the entire operating range is 10µA.
The TMP102 device is suitable for extended temperature measurement in a variety of communications, computers, consumer products, environmental, industrial, and instrumentation applications. The device's rated operating temperature range is –40°C to 125°C.
The TMP102 production unit has undergone 100% sensor testing, has NIST traceability features, and has been verified using NIST traceable equipment using the calibration requirements recognized by the ISO/IEC 17025 standard.

The LM3xxLV family includes the single LM321LV, dual LM358LV, and quad LM324LV operational amplifiers, or op amps. The devices operate from a low voltage of 2.7 V to 5.5 V.
TCA9534A is a 16-pin device that provides 8-bit general-purpose parallel input and output (I/O) expansion for the two-wire bidirectional I 2C bus (or SMBus) protocol. The device can operate in a supply voltage range of 1.65V to 5.5V, allowing the use of various devices. The device supports 100kHz (standard mode) and 400kHz (fast mode) clock frequencies. When switches, sensors, buttons, LEDs, fans, and other similar devices require additional I/O, I/O expanders (such as TCA9534A) can provide a simple solution.
The TLC5941 is a 16-channel, constant-current sink, LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness variations between LED channels and other LED Controlled In-Rush Current drivers. Both grayscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels.
The TPS6104x is a high-frequency boost converter dedicated for small to medium LCD bias supply and white LED backlight supplies. The device is ideal to generate output voltages up to 28 V from a dual-cell NiMH/NiCd or a single-cell Li-Ion battery. The part can also be used to generate standard 3.3-V or 5-V to 12-V power conversions.
The TL431 and TL432 are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges.
8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROLThe TLC548 and TLC549 are CMOS analog-to-digital converter (ADC) integrated circuits built around an 8-bitswitched-capacitor successive-approximation ADC. These devices are designed for serial interface with amicroprocessor or peripheral through a 3-state data output and an analog input. The TLC548 and TLC549 useonly the input/output clock (I/O CLOCK) input along with the chip select (CS) input for data control. Themaximum I/O CLOCK input frequency of the TLC548 is 2.048 MHz, and the I/O CLOCK input frequency of theTLC549 is specified up to 1.1 MHz.
Description This device contains four independent buffers with 3-state outputs. Each gate performs the Boolean function Y = A in positive logic.
TL431LI/TL432LI is a pin-to-pin replacement of TL431/TL432. TL43xLI provides better stability, lower temperature drift (VI(dev)) and lower reference current (Iref), thereby improving system accuracy.TL431 and TL432 devices are three-terminal adjustable shunt regulators, which can meet the specified thermal stability in the applicable automotive, commercial and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5V) and 36V through two external resistors.
