DESCRIPTION
The TS612 is a dual operational amplifier featur-
ing a high output current (200mA min.), large
gain-bandwidth product (130MHz) and capable of
driving a 25Ω load with a 160mA output current at
±6V
power supply.
This device is particularly intended for applications
where multiple carriers must be amplified simulta-
neously with very low intermodulation products.
The TS612 is housed in SO20 batwing plastic
package for a very low thermal resistance.
The TS612 is fitted out with Power Down function
in order to decrease the consumption.

1. All voltages values, except differential voltage are with respect to network terminal.
2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
CC
+0.3V.
4. An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating.
Destructive dissipation can result from short circuit on amplifiers.

OUPUT IMPEDANCE IN POWER DOWN MODE
In Power Down Mode the output of the driver is in
"high impedance" state. It is really the case for the
static mode. Regarding the dynamic mode, the im-
pedance decreases due to a capacitive effect of
the collector-substrat and base collector junction.
The impedance behaviour comes capacitive, typi-
cally: 1.4MΩ // 33pF.
INTERMODULATION DISTORTION
The curves shown below are the measurements
results of a single operator wired as an adder with
a gain of 15dB.
The operational amplifier is supplied by a symmet-
ric
±6V
and is loaded with 25Ω.
Two synthesizers (Rhode & Schwartz SME) gen-
erate two frequencies (tones) (70 & 80kHz or 180
& 280kHz).
An HP3585 spectrum analyzer measures the spu-
rious level at different frequencies.
The curves are traced for different output levels
(the value in the X ax is the value of each tone).
The output levels of the two tones are the same.
The generators and spectrum analyzer are phase
locked to enhance measurement precision.
