3 Description

The LMH6723/LMH6724 provides a 260 MHz small signal bandwidth at a gain of +2 V/V and a 600 V/μs slew rate while consuming only 1 mA from ±5V supplies.

The LMH6723/LMH6724 supports video applications with its 0.03% and 0.11° differential gain and phase for NTSC and PAL video signals, while also offering a flat gain response of 0.1 dB to 100 MHz. Additionally, the LMH6723/LMH6724 can deliver 110 mA of linear output current. This level of performance, as well as a wide supply range of 4.5 to 12V, makes the LMH6723/LMH6724 an ideal op amp for a variety of portable applications. With small packages (SOIC and SOT-23), low power requirement, and high performance, the LMH6723/LMH6724 serves a wide variety of portable applications.

The LMH6723/LMH6724 is manufactured in Texas Instruments' VIP10 complimentary bipolar process.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications, see the Electrical Characteristics tables.
(3) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. See Application and Implementation for information on temperature derating of this device. Min/Max ratings are based on product characterization and simulation. Individual parameters are tested as noted.
(4) The maximum continuous output current (IOUT) is determined by device power dissipation limitations. See Power Supply Recommendations for more details.
(5) Human Body Model, 1.5 kΩ in series with 100 pF. Machine Model, 0Ω In series with 200 pF.
