μPC842, μPC4742
Single Power Supply, High Speed, Wide Band,
Dual Operational Amplifier
DESCRIPTION
μPC842 and μPC4742 are high-speed versions of single-power general-purpose operational amplifiers
μPC1251 and μPC358, achieving high-speed pulse response characteristics and high stability. A high speed
PNP transistor is used in the circuit which improves the characteristics such as a slew rate, gain-bandwidth
product, stabilization of the withstand load capacitance, with no crossover distortion compared to μPC1251,
μPC358.
Therefore, it can be used widely for various application circuits such as single power supply AC amplifier,
active filter, line driver, amplifier for light receiving element, etc.
Depending on the usage and operating ambient temperature range, the μPC842 are designed for extended
temperature and suited for wide operating ambient temperature application, and μPC4742 is design for general
purposes.
Along with this series of lineup, the quad type operational amplifier, μPC844, μPC4744 with the same circuit
configuration are also available.

This is the input voltage range that can be applied to the input terminal without any characteristics
degradation or breakdown. It can be applied regardless of the supply voltage. Do not apply the voltage
below V-(GND)-0.3V. The operational amplifier electrical characteristics will operate normally when the
input voltage is operating within the common-mode input voltage range.
Voltage range that can be applied externally to the output terminal without deteriorating or damage to
the product. It can be applied regardless of the power supply. Caution not to exceed the ratings, including
transient conditions such as when the power supply is ON/OFF.
This is the value when mounting the glass epoxy board (size 100 mm x 100 mm, thickness 1 mm, and
copper foil only on one side with 15% solid wiring of the board area). Please take note that depending
on the operating ambient temperature, each product following conditions and de-rating rate as below:
