ELECTRICAL CHARACTERISTICS: VS = +2.7V to +5.5V

Boldface limits apply over the specified temperature range, TA = –40°C to +85°C.

At TCASE = +25°C, RL = 1kΩ, and connected to VS/2, unless otherwise noted.

NOTES:

(1) See typical characteristic,

Maximum Output Voltage vs Frequency.

(2) See typical characteristic,

Total Harmonic Distortion + Noise vs Frequency.

(3) Swing to the rail is measured in final test. Under those conditions, the AOL is derived from characterization.

(4) See Safe Operating Area (SOA) plots.

(5) See typical characteristic,

Overshoot vs Load Capacitance.

(6) See the

Typical Characteristics section. Higher frequency output impedance can affect frequency stability.

(7) External current limit setting resistor is required; see Figure 1.

(8) ILIMIT is the value of the desired current limit and is equal to 9800(ISET), where ISET is the current through the ISET pin. ILIMIT tolerance is proportional to the ratio of

ILIMIT/ISET. Errors from this parameter can be calibrated out—see the Applications Information section.

(9) VSET is a voltage reference that equals the difference between the voltage of the ISET pin and V–, and is referenced to the negative rail. Errors from this parameter

can be calibrated out—see the

Applications Information section.
