Incremental circuit internal encoder photo IC

Incremental circuit internal encoder photo IC

A photo IC for optical encoders that enables miniaturization and low power consumption through chip integration!

This is a photo IC for optical encoders that incorporates a light-receiving element, amplification circuit, and multiplication circuit. The multiplication factor can be switched externally. Since it is a semi-custom design focusing only on the light-receiving section, the design and development period can be significantly shortened. By integrating it into a single chip, it becomes possible to reduce size and power consumption. 【Features】 - Capable of monitoring analog waveforms - External terminals allow switching between 1x, 2x, 4x, and 8x multiplication - Space-saving BGA package / lead-free *For more details, please contact us or download and view the catalog.

Schmitt trigger circuit photo IC 'CPS253AL/BL'

Schmitt trigger circuit photo IC 'CPS253AL/BL'

The package is a small 4-pin surface mount type! Introducing the Schmitt trigger circuit photo IC.

The "CPS253AL/BL" is a digital output type photo IC that integrates a photodiode, amplification circuit, Schmitt trigger circuit, and output transistor into a single chip. It exhibits minimal sensitivity variation due to power supply changes across a wide operating voltage range. The output format is open collector, with "CPS253AL" outputting a high level when light is input, and "CPS253BL" outputting a low level when light is input. 【Features】 ■ Compact transparent COB package (2.0mm × 2.0mm × 1.0mm, 4 pins, no lens) ■ High-speed response ■ Wide operating voltage range of 3.0V to 13.2V ■ Threshold irradiance independent of supply voltage ■ Digital output (open collector) *For more details, please refer to the PDF document or feel free to contact us.

Photo IC for Laser Power Monitor 'CPF233AL'

Photo IC for Laser Power Monitor 'CPF233AL'

Photo IC suitable for small, thin laser power monitors!

The "CPF233AL" is an OEIC developed for controlling laser power across three wavelengths for front monitoring. It features a serial interface, allowing for the selection of four gain modes (coarse gain adjustment) and gain adjustment of ±4.7dB (fine gain adjustment). With the adoption of a COB-8PIN (2.4mm×2mm) package, it is suitable for compact and slim pickups. 【Specifications】 ■ Package: 2.4mm×2mm LCOB-8 pin ■ Wavelength compatibility: 405 nm, 650 nm, 780 nm ■ Frequency characteristics: 160[MHz] ■ Standby function: Yes ■ Built-in amplifier characteristics: Tr/Tf: 3[ns] *For more details, please contact us.

Laser power monitor photo IC 'CPF274ALK'

Laser power monitor photo IC 'CPF274ALK'

It is possible to reduce the number of components! The adoption of the LKCOB-8PIN package makes it suitable for compact and slim pickups.

The "CPF274ALK" is an OEIC developed for front monitoring to control the laser power of pickups for BD/DVD/CD with a single IC. It features a serial interface, allowing for the selection of five gain modes (coarse gain adjustment) and gain adjustment of ±4.7dB (fine gain adjustment). Additionally, it eliminates the need for variable resistors for gain adjustment, reducing the number of components. With a high-speed amplifier integrated into the PIN photodiode, it achieves low output impedance and stable output. 【Features】 ■ Equipped with a serial interface ■ Capable of selecting five gain modes and adjusting gain by ±4.7dB ■ Reduces the number of components ■ High-speed amplifier integrated into the PIN photodiode ■ Achieves low and stable output *For more details, please refer to the PDF document or feel free to contact us.
