LMH6657/LMH6658 270MHz Single Supply, Single & Dual Amplifiers

Check for Samples: LMH6657, LMH6658

FEATURES

DESCRIPTION

The LMH6657/6658 are low-cost operational

amplifiers that operate from a single supply with input

voltage range extending below the V⁻. Based on easy

to use voltage feedback topology and boasting fast

slew rate (700V/µs) and high speed (140MHz

GBWP), the LMH6657 (Single) and LMH6658 (dual)

can be used in high speed large signal applications.

V_S= 5V, T_A= 25°C, R_L= 100Ω (Typical Values

Unless Specified)

•

−3dB BW (A_V= +1) 270MHz

Supply Voltage Range 3V to 12V

Slew Rate, (V_S= ±5V) 700V/µs

Supply Current 6.2mA/amp

Output Current +80/−90mA

These

applications

include

instrumentation,

communication devices, set-top boxes, etc.

Input Common Mode volt. 0.5V Beyond V⁻,

With a -3dB BW of 100MHz (A_V= +2) and DG & DP

of 0.03% & 0.10° respectively, the LMH6657/6658

are well suited for video applications. The output

stage can typically supply 80mA into the load with a

swing of about 1V from either rail.

1.7V from V⁺

•

Output Voltage Swing (R_L= 2kΩ) 0.8V from

Rails

•

Input Voltage Noise 11nV/√Hz

Input Current Noise 2.1pA√Hz/

DG Error 0.03%

For Industrial applications, the LMH6657/6658 are

excellent cost-saving choices. Input referred voltage

noise is low and the input voltage can extend below

V⁻to ease amplification of low level signals that could

be at or near the system ground. With low distortion

and fast settling, LMH6657/6658 can provide

buffering for A/D and D/A applications.

DP Error 0.10°

THD (5MHz) −55dBc

Settling Time (0.1%) 37ns

Fully Characterized for 5V, and ±5V

Output Overdrive Recovery 18ns

Output Short Circuit Protected⁽¹⁾

The LMH6657/6658 versatility and ease of use is

extended even further by offering these high slew

rate , high speed Op Amps in miniature packages

such as SOT-23-5, SC70, SOIC-8, and VSSOP-8.

Refer to the Ordering Information section for

packaging options available for each device.

No Output Phase Reversal with CMVR

Exceeded

APPLICATIONS

•

CD/DVD ROM

ADC Buffer Amp

Portable Video

Current Sense Buffer

Portable Communications

(1) Short Circuit Test is a momentary test.
