3 Description

The LMH6702-MIL is a very wideband, DC-coupled monolithic operational amplifier designed specifically for wide dynamic range systems requiring exceptional signal fidelity. Benefitting from current feedback architecture, the LMH6702-MIL offers unity gain stability at exceptional speed without need for external compensation.

With its 720-MHz bandwidth (A_V = 2 V/V, V_O = 2 V_PP), 10-bit distortion levels through 60-MHz (R_L = 100 Ω), 1.83-nV/√Hz input referred noise and 12.5-mA supply current, the LMH6702-MIL is the ideal driver or buffer for high-speed flash A-D and D-A converters.

Wide dynamic range systems such as radar and communication receivers that require a wideband amplifier offering exceptional signal purity will find the low input referred noise and low harmonic and intermodulation distortion of the LMH6702-MIL an attractive high speed solution.

The LMH6702-MIL is constructed using VIP10™ complimentary bipolar process and proven current feedback architecture. The LMH6702-MIL is available in SOIC and SOT-23 packages.
