1.8V, 700nA, Zer ø -Crossover

RAIL-TO-RAIL I/O OPERATIONAL AMPLIFIER

• nanoPOWER:

The OPA369 and OPA2369 are ultra-low-power,

low-voltage operational amplifiers from Texas

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

noise 3.6 µ V

(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.

OPA369 OPA2369 www.ti.com ............................................................................................................................................ SBOS414B – AUGUST 2007 – REVISED DECEMBER 2008 APPLICATION INFORMATION The OPA369 family of operational amplifiers minimizes power consumption and operates on supply voltages as low as 1.8V. Power-supply rejection ratio (PSRR), common-mode rejection ratio (CMRR), and open-loop gain (AOL) typical values are in the range of 100dB or better.

SBOS414B – AUGUST 2007 – REVISED DECEMBER 2008 WINDOW COMPARATOR If VIN falls below VL, the output of A2 is high, current flows through D2, and VOUT is low. Likewise, if VIN rises above VH, the output of A1 is high, current flows through D1, and VOUT is low.
