LMH6702

Ultra Low Distortion, Wideband Op Amp

General Description

Features

The LMH6702 is a very wideband, DC coupled monolithic

operational amplifier designed specifically for wide dynamic

range systems requiring exceptional signal fidelity. Benefit-

ing from National’s current feedback architecture, the

LMH6702 offers unity gain stability at exceptional speed

without need for external compensation.

V_S

5V, T_A= 25˚C, A_V= +2V/V, R_L= 100Ω, V_OUT= 2V_PP

Typical unless Noted:

n 2^nd/3^rdHarmonics (5MHz, SOT23-5)

n −3dB Bandwidth (V_OUT= 2V_PP

n Low noise

n Fast settling to 0.1%

n Fast slew rate

n Supply current

n Output current

n Low Intermodulation Distortion (75MHz)

)

With its 720MHz bandwidth (A_V= 2V/V, V_O= 2V_PP), 10-bit

distortion levels through 60MHz (R_L= 100Ω), 1.83nV/

input referred noise and 12.5mA supply current, the

LMH6702 is the ideal driver or buffer for high-speed flash

A/D and D/A converters.

n Improved Replacement for CLC409 and CLC449

Wide dynamic range systems such as radar and communi-

cation receivers, requiring a wideband amplifier offering ex-

ceptional signal purity, will find the LMH6702’s low input

referred noise and low harmonic and intermodulation distor-

tion make it an attractive high speed solution.

Applications

n Flash A/D driver

n D/A transimpedance buffer

n Wide dynamic range IF amp

n Radar/communication receivers

n Line driver

™

The LMH6702 is constructed using National’s VIP10 com-

plimentary bipolar process and National’s proven current

feedback architecture. The LMH6702 is available in SOIC

and SOT23-5 packages.
