LMH6642/6643/6644

3V, Low Power, 130MHz, 75mA Rail-to-Rail Output

Amplifiers

in single (LMH6642), dual (LMH6643), and quad (LMH6644)

options. See ordering information for packages offered.

General Description

The LMH664X family true single supply voltage feedback

amplifiers offer high speed (130MHz), low distortion

(−62dBc), and exceptionally high output current (approxi-

mately 75mA) at low cost and with reduced power consump-

tion when compared against existing devices with similar

performance.

Features

(V_S

5V, T_A= 25˚C, R_L= 2kΩ, A_V= +1. Typical values

unless specified).

n −3dB BW (A_V= +1)

130MHz

3V to 12.8V

130V/µs

Input common mode voltage range extends to 0.5V below V⁻

and 1V from V⁺. Output voltage range extends to within

40mV of either supply rail, allowing wide dynamic range

especially desirable in low voltage applications. The output

stage is capable of approximately 75mA in order to drive

heavy loads. Fast output Slew Rate (130V/µs) ensures large

peak-to-peak output swings can be maintained even at

higher speeds, resulting in exceptional full power bandwidth

of 40MHz with a 3V supply. These characteristics, along with

low cost, are ideal features for a multitude of industrial and

commercial applications.

n THD (5MHz, R_L= 2kΩ, V_O= 2V_PP, A_V= +2)

n Settling time

68ns

Careful attention has been paid to ensure device stability

under all operating voltages and modes. The result is a very

well behaved frequency response characteristic (0.1dB gain

flatness up the 12MHz under 150Ω load and A_V= +2) with

minimal peaking (typically 2dB maximum) for any gain set-

ting and under both heavy and light loads. This along with

fast settling time (68ns) and low distortion allows the device

to operate well in ADC buffer, and high frequency filter

applications as well as other applications.

n Fully characterized for 3V, 5V, and 5V

n Overdrive recovery

100ns

n Output short circuit protected (Note 11)

n No output phase reversal with CMVR exceeded

Applications

n Active filters

n CD/DVD ROM

n ADC buffer amp

n Portable video

n Current sense buffer

This device family offers professional quality video perfor-

mance with low DG (0.01%) and DP (0.01˚) characteristics.

Differential Gain and Differential Phase characteristics are

also well maintained under heavy loads (150Ω) and through-

out the output voltage range. The LMH664X family is offered

Closed Loop Gain vs. Frequency for Various Gain
