NOTES:

2. Suggested VOS Adjust Circuit: The inverting input current (-IBIAS) can be adjusted with an external 10kΩ pot between pins 1 and 5, wiper

connected to V+. Since -IBIAS flows through the feedback resistor (RF), the result is an adjustment in offset voltage. The amount of offset voltage

adjustment is determined by the value of RF (∆VOS = ∆-IBIAS*RF).

3. RL = 100Ω, VIN = 10V. This is the minimum current which must be pulled out of the Disable pin in order to disable the output. The output is

considered disabled when -10mV

≤ VOUT ≤ +10mV.

4. VIN = 0V. This is the maximum current that can be pulled out of the Disable pin with the HA-5020 remaining enabled. The HA-5020 is considered

disabled when the supply current has decreased by at least 0.5mA.

5. VOUT switches from -10V to +10V, or from +10V to -10V. Specification is from the 25% to 75% points.

6.

7. RL = 100Ω, VOUT = 1V. Measured from 10% to 90% points for rise/fall times; from 50% points of input and output for propagation delay.

8. This parameter is not tested. The limits are guaranteed based on lab characterization, and reflect lot-to-lot variation.

9. VIN = +10V, Disable = +15V to 0V. Measured from the 50% point of Disable to VOUT = 0V.

10. VIN = +10V, Disable = 0V to +15V. Measured from the 50% point of Disable to VOUT = 10V.

11. VIN = 0V, Force VOUT from 0V to ±10V, tR = tF = 50ns.

12. Measured with a VM700A video tester using a NTC-7 composite VITS.

13. See “Typical Performance Curves” for more information.

14. VCM = ±2.5V. At -40°C product is tested at VCM = ±2.25V because short test duration does not allow self heating.

15. RL = 100Ω. VIN = 2.5V. This is the minimum current which must be pulled out of the Disable pin in order to disable the output. The output is

considered disabled when -10mV

≤ VOUT ≤ +10mV.

16. VOUT switches from -2V to +2V, or from +2V to -2V. Specification is from the 25% to 75% points.

17. FPBW =

.

18. VIN = 0V, Force VOUT from 0V to ±2.5V, tR = tF = 50ns.

19. VIN = +2V, Disable = +5V to 0V. Measured from the 50% point of Disable to VOUT = 0V.

20. VIN = +2V, Disable = 0V to +5V. Measured from the 50% point of Disable to VOUT = 2V.

Electrical Specifications V+ = +5V, V- = -5V, R

F = 1kΩ, AV = +1, RL = 400Ω, CL ≤10pF, Unless Otherwise Specified.

Parameters are not tested. The limits are guaranteed based on lab characterizations, and reflect

lot-to-lot variation. (Continued)
