necessarily include testing of all parameters.
DESCRIPTION
The OPA369 and OPA2369 are ultra-low-power,
low-voltage
Instruments designed especially for battery-powered
applications.
The OPAx369 operates on a supply voltage as low as
1.8V and has true rail-to-rail operation that makes it
useful for a wide range of applications. The
zerø-crossover feature resolves the problem of input
crossover distortion that becomes very prominent in
low voltage (< 3V), rail-to-rail input applications.
In addition to microsize packages and very low
quiescent current, the OPAx369 features 12kHz
bandwidth, low offset drift (1.75 V/°C, max), and low
noise 3.6 V
The OPA369 (single version) is offered in an SC70-5
package. The OPA2369 (dual version) comes in both
MSOP-8 and SOT23-8 packages.
