100MHz Current Feedback
Video Amplifier With Disable
The HA-5020 is a wide bandwidth, high slew rate amplifier
optimized for video applications and gains between 1 and
10. Manufactured on Intersil’s Reduced Feature
Complementary Bipolar DI process, this amplifier uses
current mode feedback to maintain higher bandwidth at a
given gain than conventional voltage feedback amplifiers.
Since it is a closed loop device, the HA-5020 offers better
gain accuracy and lower distortion than open loop buffers.
The HA-5020 features low differential gain and phase and
will drive two double terminated 75coax cables to video
levels with low distortion. Adding a gain flatness
performance of 0.1dB makes this amplifier ideal for
demanding video applications. The bandwidth and slew rate
of the HA-5020 are relatively independent of closed loop
gain. The 100MHz unity gain bandwidth only decreases to
60MHz at a gain of 10. The HA-5020 used in place of a
conventional op amp will yield a significant improvement in
the speed power product. To further reduce power, HA-5020
has a disable function which significantly reduces supply
current, while forcing the output to a true high impedance
state. This allows the outputs of multiple amplifiers to be
wire-OR’d into multiplexer configurations. The device also
includes output short circuit protection and output offset
voltage adjustment.
For multi channel versions of the HA-5020 see the HA5022
dual with disable, HA5023 dual, HA5013 triple and HA5024
quad with disable op amp data sheets.

NOTES:
2. Suggested VOS Adjust Circuit: The inverting input current (-IBIAS) can be adjusted with an external 10kpot 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 = 100, 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. FPBW = S-2---πl--e--V-w----P--R-E---a-A---t-Ke-- ; VPEAK = 10V.
7. RL = 100, 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 -40oC product is tested at VCM = ±2.25V because short test duration does not allow self heating.
15. RL = 100. 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 = S-2---πl--e--V-w---P---R-E---a-A---t-Ke-- ; VPEAK = 2V .
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.
