SNOSB18I –APRIL 2010–REVISED DECEMBER 2014

LMH6629 Ultra-Low Noise, High-Speed Operational Amplifier with Shutdown

1 Features

3 Description

The LMH6629 is a high-speed, ultra-low noise

amplifier designed for applications requiring wide

bandwidth with high gain and low noise such as in

communication, test and measurement, optical and

ultrasound systems.

•

Specified for V_S= 5 V, R_L= 100 Ω, A_V= 10V/V

WSON-8 Package, unless Specified. –3dB

Bandwidth 900 MHz

•

Input Voltage Noise 0.69 nV/√Hz

Input Offset Voltage Max. Over Temperature ±0.8

The LMH6629 operates on 2.7-V to 5.5-V supply with

an input common mode range that extends below

ground and outputs that swing to within 0.8 V of the

rails for ease of use in single supply applications.

Heavy loads up to ±250 mA can be driven by high-

frequency large signals with the LMH6629's –3dB

bandwidth of 900 MHz and 1600 V/µs slew rate. The

LMH6629 (WSON-8 package only) has user-

selectable internal compensation for minimum gains

of 4 or 10 controlled by pulling the COMP pin low or

high, thereby avoiding the need for external

compensation capacitors required in competitive

devices. Compensation for the SOT-23-5 package is

internally set for a minimum stable gain of 10 V/V.

The WSON-8 package also provides the power-down

enable/disable feature.

•

Slew Rate 1600 V/ μs

HD2 @ f = 1 MHz, 2V_PP−90 dBc

HD3 @ f = 1 MHz, 2V_PP−94 dBc

Supply Voltage Range 2.7 V to 5.5 V

Typical Supply Current 15.5 mA

Selectable Min. Gain ≥4 or ≥10 V/V

Enable Time: 75 ns

Output Current ±250 mA

WSON-8 and SOT-23-5 Packages

2 Applications

•

Instrumentation Amplifiers

Ultrasound Pre-amps

Wide-band Active Filters

Opto-Electronics

The low-input noise (0.69 nV/√Hz and 2.6 pA/√Hz),

low distortion (HD2/HD3 = −90 dBc/−94 dBc) and

ultra-low DC errors (800 µV V_OSmaximum over

temperature, ±0.45 µV/°C drift) allow precision

operation in both ac- and dc-coupled applications.

Medical Imaging Systems

Base-Station Amplifiers

The LMH6629 is fabricated in Texas Instruments'

proprietary SiGe process and is available in a 3 mm ×

3 mm 8-pin WSON package as well as the SOT-23-5

package.
