Notes
1. The DC output voltage with respect to ground is approximately 0.5VCC.
2. The frequency response is externally fixed by the input coupling capacitors.
3. The noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz (unweighted).
4. The common-mode rejection ratio is measured at the output with a voltage source of 1 V (RMS) in accordance with
the test circuit (see Fig.3) while VINL and VINR are shorted-circuited. Frequencies between 100 Hz and 100 kHz.
5. The ripple rejection is measured at the output, with Rs = 2 kΩ, f = 1 kHz and a ripple amplitude of 2 V (p-p).
6. The ripple rejection is measured at the output, with Rs = 0 to 2 kΩ, f = 100 Hz to 20 kHz and a maximum ripple
amplitude of 2 V (p-p).

Product specification
This data sheet contains target or goal specifications for product development.
This data sheet contains preliminary data; supplementary data may be published later.
This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices, or systems where malfunction of these
products can reasonably be expected to result in personal injury. Philips customers using or selling these products for
use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such
improper use or sale.
