General Description
AH266 is an integrated Hall sensor with output drivers designed for electronic commutation of
brush-less DC motor applications. The device includes an on-chip Hall voltage generator for
magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide
switching hysteresis for noise rejection, and complementary darlington open-collector drivers for sinking large current loads. An internal bandgap regulator is used to provide temperature
compensated supply voltage for internal circuits and allows a wide operating supply range.
If a magnetic flux density (B) is larger than operate point (Bop), DO turn on (low) and DOB turn off (high). The outputs state is latched prior to reach release point (Brp). if B< Brp, DO turn off and DOB turn on. AH266 is rated for operation over temperature range from -20oC to 85 oC and voltage range from 4V to 28V. The devices are available in low cost die forms or rugged 4 pin SIP packages.

General Description
The AMIS-42671 CAN transceiver with autobaud is the interface between a controller area network (CAN) protocol controller and the physical bus. It may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42671 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.
The AMIS-42671 is primarily intended for industrial network applications where long network lengths are mandatory. Examples are elevators, in-building networks, process control and trains. To cope with the long bus delay the communication speed needs to be low. AMIS-42671 allows low transmit data rates down 10 Kbit/s or lower. The autobaud function allows the CAN controller to determine the incoming baud rate without influencing the CAN communication on the bus.

Key Features
*Fully compatible with the ISO 11898-2 standard
*Autobaud function
*Wide range of bus communication speed (0 up to 1 Mbit/s)
*Allows low transmit data rate in networks exceeding 1 km
*Ideally suited for 12V and 24V industrial and automotive applications
*Low electromagnetic emission (EME) common-mode choke is no longer required
*Differential receiver with wide common-mode range (+/- 35V) for high EMS
*No disturbance of the bus lines with an un-powered node
*Thermal protection
*Bus pins protected against transients
*Silent mode in which the transmitter is disabled
*Short circuit proof to supply voltage and ground
*Logic level inputs compatible with 3.3V devices
*ESD protection for CAN bus at ± 8 kV

General Description
The MAX8741/MAX8742 are buck-topology, step-down, switch-mode, power-supply controllers that generate logic-supply voltages in battery-powered systems. These high-performance, dual/triple-output devices include onboard power-up sequencing, power-good signaling with
delay, digital soft-start, secondary winding control, lowdropout circuitry, internal frequency-compensation networks, and automatic bootstrapping.
Up to 97% efficiency is achieved through synchronous rectification and Maxim’s proprietary Idle Mode™ control scheme. Efficiency is greater than 80% over a 1000:1 load-current range, which extends battery life in system suspend or standby mode. Excellent dynamic response corrects output load transients within five clock cycles.
Strong 1A on-board gate drivers ensure fast external n-channel MOSFET switching.
These devices feature a logic-controlled and synchronizable, fixed-frequency, pulse-width-modulation (PWM) operating mode. This reduces noise and RF interference in sensitive mobile communications and pen-entry applications.
Asserting the SKIP pin enables fixed-frequency mode, for lowest noise under all load onditions.
The MAX8741/MAX8742 include two PWM regulators, adjustable from 2.5V to 5.5V with fixed 5.0V and 3.3V modes. All these devices include secondary feedback regulation, and the MAX8742 contains a 12V/120mA linear regulator. The MAX8741 includes a secondary feedback
input (SECFB), plus a control pin (STEER) that selects which PWM (3.3V or 5V) receives the secondary feedback signal. SECFB provides a method for adjusting the secondary winding voltage regulation point with an external resistor-divider, and is intended to aid in creating
auxiliary voltages other than fixed 12V.
The MAX8741/MAX8742 contain internal output overvoltage- and undervoltage-protection features.

Quality, low cost, bipolar fabrication with innovative design concepts are employed for the TL33071/2/4, TL34071/2/4, and TL35071/2/4 series of monolithic operational amplifiers. This series of operational amplifiers offers 4.5 MHz of gain bandwidth product, 13 V/ms slew rate, and fast settling time without the use of JFET device technology. Although this series can be operated from split supplies, it is particularly suited for single-supply operation since the common-mode input voltage range includes ground potential (VCC–). With a Darlington transistor input stage, this series exhibits high input resistance, low input offset voltage, and high gain.
 The all-npn output stage, characterized by no dead-band crossover distortion and large output voltage swing, provides high-capacitance drive capability, excellent phase and gain margins, low open-loop high-frequency output impedance, and symmetrical source/sink ac frequency response. The TL34071/2/4 devices are avaliable in standard or prime performance (A-suffix) grades and are specified over the commercial (0°C to 70°C) temperature range. The TL33071/2/4 devices are available in standard or prime performance (A-suffix) grades and are specified over industrial/vehicular (–40°C to 105°C) temperature range. The TL35071/2/4 devices are avaliable in standard or prime performance (A-suffix) grades and are specified over the military (–55°C to 125°C) temperature range.
 These low-cost amplifiers are available in single, dual, and quad configurations and are pin compatible with the MC33071/2/4, MC34071/2/4, and MC35071/2/4 series of amplifiers. Packaging options include standard plastic DIP and SO packages.
