General Description
The COMLINEAR CLC1020 is a single channel, high-performance, voltage
feedback amplifier. The CLC1020 provides 2.1MHz gain bandwidth product
and 2.7V/μs slew rate making it well suited for high-performance battery
powered-systems. This COMLINEAR high-performance amplifier also offers
low input offset voltage and low bias current.
The COMLINEAR CLC1020 consumes only 127μA supply current and is
designed to operate from a supply range of 2.7V to 5.5V (±1.35 to ±2.75).
The input voltage range extends 400mV below the negative rail and 700mV
below the positive rail. The CLC1020 amplifier operates over the extended
temperature range of -40°C to +125°C.
The CLC1020 is packaged in the space saving TSOT-5 package. The TSOT-5
package is pin compatible with the SOT23-5 package.

General Description
+Vs
6.8µF
The CLC1020 is a single supply, general purpose, voltage-
feedback amplifier fabricated on a CMOS process. The
CLC1020 offers 2.1MHz gain bandwidth product, 2.7V/μs
slew rate, and only 127μA supply current. It features a rail to
rail output stage and is unity gain stable.
The common mode input range extends to 400mV below
ground and to 700mV below Vs. Exceeding these values
will not cause phase reversal. However, if the input voltage
exceeds the rails by more than 0.5V, the input ESD devices
will begin to conduct. The output will stay at the rail during
this overdrive condition.
The output stage is short circuit protected and offers “soft”
saturation protection that improves recovery time. Figures
1, 2, and 3 illustrate typical circuit configurations for non-
inverting, inverting, and unity gain topologies for dual supply
applications. They show the recommended bypass capacitor
values and overall closed loop gain equations. Figure 4
shows the typical non-inverting gain circuit for single supply
applications

Power Dissipation
Power dissipation should not be a factor when operating
under the stated 2kΩ load condition. However, applications
with low impedance, DC coupled loads should be analyzed
to ensure that maximum allowed junction temperature
is not exceeded. Guidelines listed below can be used to
verify that the particular application will not cause the
device to operate beyond its intended operating range.

Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction
temperature, the package thermal resistance value
ThetaJA (ӨJA) is used along with the total die power
dissipation.
TJunction = TAmbient + (ӨJA × PD)
Where TAmbient is the temperature of the working environment.
In order to determine PD, the power dissipated in the load
needs to be subtracted from the total power delivered by
