Product details

A 57 V/µs slew rate means the output can swing 5 V in about 88 ns, which supports full-power bandwidth into the tens of MHz for video or pulse waveforms. For a 2 Vpp output swing, the large-signal bandwidth is roughly 4.5 MHz — enough for composite video or fast ADC input buffers. The 35 mA output current per channel drives 50 Ω loads or multiple ADC inputs directly.

Supply range and input offset

The 2.7 V minimum supply lets the part operate from a single lithium-ion cell or a 3.3 V rail with headroom. Input offset voltage is 100 µV typical, which keeps DC errors low in precision gain stages. Input bias current is 1.4 µA — a bipolar input stage, so source impedance matters: keep feedback resistors below 10 kΩ to avoid offset drift from bias current.

Lifecycle and compliance

The NOPB suffix confirms lead-free (Pb-free) finish per TI's green packaging directive.

Frequently asked questions

What is the difference between LMH6619 and LMH6618?

The LMH6618 is a single-channel version of the same voltage-feedback amplifier core; the LMH6619 provides two amplifiers in one 8-SOIC package. All other key specifications — 140 MHz bandwidth, 57 V/µs slew rate, rail-to-rail output, 2.7 V to 11 V supply — are identical between the two.

Can LMH6619 be used as a comparator?

The LMH6619 is not designed or specified for comparator operation. It lacks the open-collector output and hysteresis control of a dedicated comparator. Using it open-loop as a comparator risks phase inversion and excessive propagation delay; a proper comparator like the TLV3501 is a better fit for that function.
