APPLICATION INFORMATION
DESCRIPTION
The OPA209 series of precision operational
amplifiers are unity-gain stable, and free from
unexpected output and phase reversal. Applications
with noisy or high-impedance power supplies require
decoupling capacitors placed close to the device pins.
In most cases, 0.1mF capacitors are adequate.
shows a simplified schematic of the
OPA209. This die uses a SiGe bipolar process and
contains 180 transistors.
OPERATING VOLTAGE
The OPA209 series of op amps can be used with
single or dual supplies within an operating range of
V
S
= +4.5V (±2.25V) up to +36V (±18V). Supply
voltages higher than 40V total can permanently
damage the device; see the
table.
In addition, key parameters are assured over the
specified temperature range, T
A
= –40°C to +125°C.
Parameters that vary significantly with operating
voltage or temperature are shown in the
section of this data sheet.
