FEATURES
General Description
n Unity gain stable
n 100dB voltage gain
n 550kHz unity gain bandwidth
n 0.5mA supply current
n 20nA input bias current
n 2mV input offset voltage
n 3V to 36V single supply voltage range
The COMLINEAR CLC1050 (single), CLC2050 (dual), and CLC4050 (quad)
are voltage feedback amplifiers that are internally frequency compensated to
provide unity gain stability. At unity gain (G=1), these amplifiers offer 550kHz
of bandwidth. They consume only 0.5mA of supply current over the entire
power supply operating range. The CLC1050, CLC2050, and CLC4050 are
specifically designed to operate from single or dual supply voltages.
n ±1.5V to ±18V dual supply voltage range
n Input common mode voltage range
includes ground
n 0V to VS-1.5V output voltage swing
n CLC2050: improved replacement for
industry standard LM358
The COMLINEAR CLC1050, CLC2050, and CLC4050 offer a common mode
voltage range that includes ground and a wide output voltage swing. The
combination of low-power, high supply voltage range, and low supply current
make these amplifiers well suited for many general purpose applications and
as alternatives to several industry standard amplifiers on the market today.

industry standard LM324

Data Sheet
Layout Considerations
General layout and supply bypassing play major roles in
high frequency performance. CADEKA has evaluation
boards to use as a guide for high frequency layout and as
an aid in device testing and characterization. Follow the
www.datasheet4u.com
steps below as a basis for high frequency layout:
• Include 6.8µF and 0.1µF ceramic capacitors for power
supply decoupling
• Place the 6.8µF capacitor within 0.75 inches of the power pin
• Place the 0.1µF capacitor within 0.1 inches of the power pin
• Remove the ground plane under and around the part,
especially near the input and output pins to reduce para-
sitic capacitance
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more in-
formation.
Evaluation Board Information
The following evaluation boards are available to aid in the
testing and layout of these devices:

Evaluation Board Schematics
Evaluation board schematics and layouts are shown in Fig-
ures 7-14. These evaluation boards are built for dual- sup-
ply operation. Follow these steps to use the board in a
single-supply application:
1. Short -Vs to ground.
2. Use C3 and C4, if the -VS pin of the amplifier is not
directly connected to the ground plane.
