Description for the LMH6646

The LMH6645 (single) and LMH6646 (dual), rail-to-rail input and output voltage feedback amplifiers, offer high speed (55 MHz), and low voltage operation (2.7 V) in addition to micro-power shutdown capability (LMH6647, single).

Input common mode voltage range exceeds either supply by 0.3 V, enhancing ease of use in multitude of applications where previously only inferior devices could be used. Output voltage range extends to within 20 mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650 µA/amplifier, output current capability is kept at a respectable ±20 mA for driving heavier loads. Important device parameters such as BW, Slew Rate and output current are kept relatively independent of the operating supply voltage by a combination of process enhancements and design architecture.

In portable applications, the LMH6647 provides shutdown capability while keeping the turn-off current to less than 50 µA. Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during transitions. This allows the part to be used in power saving mode, as well as multiplexing applications. Miniature packages (SOT-23, VSSOP-8, and SOIC-8) are further means to ease the adoption of these low power high speed devices in applications where board area is at a premium.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
