XR-13600
Dual Operational Transconductance
Amplifier
GENERAL DESCRIPTION
The XR-13600 is a dual operational transconductance
(Norton) amplifier with predistortion diodes and non-
committed Darlington buffer outputs.
The device is especially suitable for electronically con-
trollable gain amplifiers, controlled frequency filters, an
other applications requiring current or voltage adjust-
ments.

SYSTEM DESCRIPTION
The XR-13600 consists of two programmable transcon-
ductance amplifiers with high input impedance and
push-pull outputs. The two amplifiers share common
supplies but otherwise operate independently. Each
amplifier's transconductance is directly proportional to
its applied bias current. To improve signal-to-noise per-
formance, predistortion diodes are included on the in-
puts; the use of these diodes results in a 10 dB im-
provement referenced to 0.5% THD. Independent
Darlington emitter followers are included to buffer the
outputs.

TEST CIRCUITS
LEAKAGE CURRENT TEST CIRCUIT
Note 1. For selections to a supply voltage above ± 22
V, contact factory.
Note 2. For operating at high temperatures, the device
may be derated based on a 150°C maximum
junction temperature and a thermal resistance
of 175° C/W which applies for the device sol-
dered in a printed circuit board, operating in
still air.
Note 3. Buffer output current should be limited so as to
not exceed package dissipation.
DIFFERENTIAL INPUT CURRENT TEST CIRCUIT
-'5 V
Note 4. These specifications apply for Vee == VEE
15V, TA = 25°C, amplifier bias current (IB) =
500 #LA, pins 2 and 15 open unless otherwise
specified. The inputs to the buffers are ground-
ed and outputs are open.
Note 5. These specifications apply for VCC = VEE =
15 V, IB = 500 #LA, ROUT == 5 kO connected
from the buffer output to - VEE and the input
of the buffer is connected to the transconduct-
ance amplifier output.
