With a 6MHz full power bandwidth, this amplifier is well suited for high frequency signal conditioning circuits and video amplifiers. Gain flatness of 0.035dB, combined with differential gain and phase specifications of 0.02%, and 0.03 degrees, respectively, make the HA-2842 ideal for component and composite video applications. A zener/nichrome based reference circuit, coupled with advanced laser trimming techniques, yields a supply current with a low temperature coefficient and low lot-to-lot variability. For example, the average ICC variation from 85oC to -40oC is <600µA (±2%), while the standard deviation of the ICC distribution is <0.1mA (0.8%) at 25oC. Tighter ICC control translates to more consistent AC parameters ensuring that units from each lot perform the same way, and easing the task of designing systems for wide temperature ranges. Critical AC parameters, Slew Rate and Bandwidth, each vary by less than ±5% over the industrial temperature range (see Typical Performance Curves) Part Number Information. HA9P2842-5 (H2842F5) TEMP. RANGE (oC) 0 to 75 PACKAGE 8 Ld SOIC 1 FN2766.7 Features The HA-2842 is a wideband, high slew rate, operational amplifier featuring an outstanding combination of speed, bandwidth, and output drive capability. This amplifier’s performance is further enhanced through stable operation down to closed loop gains of +2, the inclusion of offset null controls, and by its excellent video performance.

This device features an outstanding set of AC parameters augmented by excellent output drive capability providing for suitable application in both high speed and high output drive circuits. At high output currents, especially with the 8 lead SOIC package, care must be taken to ensure that the Maximum Junction Temperature (TJ, see “Absolute Maximum Ratings” table) isn’t exceeded. As an example consider the HA-2842 in the SOIC package, with a required output current of 50mA at VOUT = 10V with ±15V supplies. The power dissipation is the quiescent power (450mW = 30V x 15mA) plus the power dissipated in the output stage (POUT = 250mW = 50mA x (15V - 10V)), or a total of 700mW. The thermal resistance (θJA) of the SOIC package is 157oC/W, which increases the junction temperature by 110oC over the ambient temperature (TA). Remaining below TJMAX requires that TA be restricted to ≤ 40oC (150oC - 110oC). Heatsinking would be required for operation at ambient temperatures greater than 40oC. Primarily intended to be used in balanced 50Ω and 75Ω coaxial cable systems as a driver, the HA-2842 could also be used as a power booster in audio systems as well as a power amp in power supply circuits. This device would also be suitable as a small DC motor driver. Prototyping Guidelines For best overall performance in any application, it is recommended that high frequency layout techniques be used. This should include: MAX POUT WITHOUT HEATSINK (VS = ±15V) TA 8 LEAD SOIC (θJA = 157oC/W) 85oC Heatsink Required 70oC 60mW 25oC 350mW 1. Mounting the device through a ground plane. 2. Connecting unused pins (NC) to the ground plane. 3. Mounting feedback components on Teflon standoffs and/or locating these components as close to the device as possible. 4. Placing power supply decoupling capacitors from device supply pins to ground. Allowable output power can be increased by decreasing the quiescent dissipation via lower supply voltages.
