Four New Driver and Sensor ICs Join Apex’s Existing Precision IC Product Offerings

Apex Microtechnology, an industry leader in precision power analog technologies, announced today the expansion of their Precision IC product line – previously comprised of nine linear amplifier ICs – to include four new driver and sensor ICs. The latest additions to the Precision IC family include an inductive proximity sensor IC, a high voltage interface IC, a 32-channel high voltage driver IC, and an 8-bit HV parallel driver IC. The new driver and sensor ICs join Apex’s existing line of linear & PWM amplifier ICs, which offer supply voltages of up to 350 V, exceptionally fast slew rates, and are available in muti-channel architectures.

“Apex Microtechnology has a long legacy of expertise in solving extremely complex power analog problems.” says Director of Business Development for Apex Microtechnology, Jens Eltze, “with feedback from our customers we have seen the market demand for solutions that solve a more generic analog and mixed signal set of design challenges. With that in mind Apex expanded our portfolio of Precision ICs to complement Apex’s hybrid product offering with highly compact, reliable, and also cost-effective options for our customers that reach a wide range of applications.”

With the addition of these new devices, Apex expands its offerings for high power, high precision requirements in applications such as; piezoelectric transduction, capacitive actuation, and LED drivers.

AIC1601: Inductive Proximity Sensor IC

Applications: Inductive Proximity Detection

The AIC1601 is a sensor IC for inductive proximity applications and can be used in conjunction with a range of inductive transducers. This IC has an analog front end, detection logic, output stage, and status LED drivers (Detection and Power) integrated.

AIC1605: High Voltage Interface IC

Applications: Inductive Proximity Detection, Optical Switch, Sensor Preamplifier, LED Driver

The AIC1605 provides high voltage N-Type and P-Type open drain outputs, a buck and linear regulator as well as two op-amps and two LED drivers. It is highly suitable for building a three-wire sensor interface. It can be used also as a supply and output stage for other applications.

AIC1532: 32-Channel High Voltage Driver

Applications: Drive of Capacitive Actuators, Piezo Transducer Excitation, Electro-Luminescent Displays

The AIC1605 is a 32-bit serial to parallel converter IC with 32 high voltage push-pull outputs and TTL compatible input signals. The outputs are designed to drive capacitive and resistive loads. An internal protection function monitors the logic supply voltage (VDD) and disables all output transistors of the high voltage push-pull outputs if an undervoltage condition is detected.

AIC1508: 8-Bit HV Parallel Driver IC

Applications: Drive of Capacitive Actuators, Piezo Transducer Excitation, Electro-Luminescent Displays

The AIC1508 is a rigid, low-cost general purpose high voltage driver IC with 8 high voltage push-pull outputs. The device has been designed for harsh industrial applications and allows wide application areas. The outputs can drive capacitive and resistive loads such as piezoelectric transducers, electroluminescent devices and micro-mechanical actuators. The maximum operating voltage is 300V, and each output has a source-sink capability of up to 40mA.
