QP Semiconductor today announced that it has completed the design and fabrication of the QP710, a socket replacement part for the LM710 Differential Voltage Comparator
The detector IC incorporates an integrated photodiode, a high-speed transimpedance amplifier, and a voltage comparator
with an output driver.
Analog peripherals include a four-channel, 12-bit analog-to-digital converter, a temperature sensor, two 12-bit digital-to-analog converters, a voltage comparator
and voltage reference.
The SC1406 integrates several functions into one chip, including two linear regulator controllers with soft start, a 5-bit VID DAC used as a programmable precision voltage reference, an ultra-fast core voltage comparator
with soft start, power good generator, and under-voltage lockout circuit.
Internal circuitry of the LM3622 includes a bandgap voltage reference, a voltage comparator
, precision voltage setting resistors and two operational amplifiers.
The SC1154 uses a high-performance, synchronous, hysteretic mode architecture that employs a voltage comparator
to provide accurate Vout.
Using fast voltage comparators
LM7219 and AD790 measured signals are compared with references (Fig.
The microcontrollers are equipped with multiple voltage comparators
and operational amplifiers, which can be applied to various high-speed samples, alarm circuits, auto-control circuits and measurement techniques, as well as fields concerning circuit break protection, quick sensors, power supply voltage supervisor circuits, zero-crossing detection circuits, etc.
