• nanoPOWER:
The OPA369 and OPA2369 are ultra-low-power,
low-voltage operational amplifiers from Texas
– OPA369: 800nA
Instruments designed especially for battery-powered
– OPA2369: 700nA/ch.
applications.
• LOW OFFSET VOLTAGE: 250 µ V
The OPAx369 operates on a supply voltage as low as
– ZERO-CROSSOVER
1.8V and has true rail-to-rail operation that makes it
• LOW OFFSET DRIFT: 0.4 µ V/ ° C
useful for a wide range of applications. The
zer ø -crossover feature resolves the problem of input
• DC PRECISION:
crossover distortion that becomes very prominent in
– CMRR: 114dB
low voltage ( < 3V), rail-to-rail input applications.
– PSRR:106dB
In addition to microsize packages and very low
– AOL: 134dB
quiescent current, the OPAx369 features 12kHz
• GAIN-BANDWIDTH PRODUCT: 12kHz
bandwidth, low offset drift (1.75 µ V/ ° C, max), and low

(0.1Hz to 10Hz).
• SUPPLY VOLTAGE: 1.8V to 5.5V
• microSIZE PACKAGES:
The OPA369 (single version) is offered in an SC70-5
package. The OPA2369 (dual version) comes in both
– SC70-5, SOT23-5, MSOP-8
MSOP-8 and SOT23-8 packages.
