DESCRIPTION
ISO213 signal isolation amplifier is a member of a
series of low-cost isolation products from Burr-Brown.
The low-profile ZIP plastic package allows PCB spac-
ings of 0.5" to be achieved, and the small footprint
results in efficient use of board space.
To provide isolation, the design uses high-efficiency,
miniature toroidal transformers in both the signal and
power paths. An uncommitted instrumentation ampli-
fier on the input and an isolated external bipolar supply
ensure the majority of input interfacing or conditioning
needs can be met.
APPLICATIONS
q INDUSTRIAL PROCESS CONTROL:
Transducer Channel Isolator for
Thermocouples, RTDs, Pressure
Bridges, Flow Meters
q 4mA TO 20mA LOOP ISOLATION
q MOTOR AND SCR CONTROL
q GROUND LOOP ELIMINATION
q ANALYTICAL MEASUREMENTS
q POWER PLANT MONITORING
q DATA ACQUISITION/TEST EQUIPMENT
ISOLATION
q MULTIPLEXED SYSTEMS WITH

NOTES: (1) Isolation-mode rejection is the ratio of the change in output voltage to a change in isolation barrier voltage. (2) Tested at 2500Vrms 50Hz limit 25µA (barrier
is essentially capacitive). (3) Nonlinearity is the peak deviation of the output voltage from the best-fit straight line. It is expressed as the ratio of deviation to FSR.
(4) Power Supply Rejection is the change in VOS /Supply Change. (5) See max VOUT and VIN vs Supply Voltage in typical performance curves. (6) Ripple is the residual
component of the barrier carrier frequency generated internally. (7) Derated at VCC < 15V. (8) FSR = Full Scale Output Range = 10V. (9) Minimum supply voltage
is given as 11.4V. This is the minimum supply to ensure a ±5V output swing can be achieved. The ISO213 actually works down to a minimum supply of 4V as shown
in the typical performance curve “Max VOUT and VIN vs Supply Voltage.”
