The LTC

®6404 is a family of AC precision, very low noise,

low distortion, fully differential input/output ampliﬁers

optimized for 3V, single supply operation.

The LTC6404-1 is unity-gain stable. The LTC6404-2 is

designed for closed-loop gains greater than or equal to

2V/V. The LTC6404-4 is designed for closed-loop gains

greater than or equal to 4V/V. The LTC6404 closed-loop

bandwidth extends from DC to 600MHz. In addition to the

normal unﬁltered outputs (OUT+ and OUT–), the LTC6404

has a built-in 88.5MHz differential single-pole lowpass

ﬁlter and an additional pair of ﬁltered outputs (OUTF+,

OUTF–). An input referred voltage noise of 1.5nV/√Hz

make the LTC6404 able to drive state-of-the-art 16-/18-bit

ADCs while operating on the same supply voltage, saving

system cost and power. The LTC6404 is characterized, and

maintains its performance for supplies as low as 2.7V and

can operate on supplies up to 5.25V. It draws only 27.3mA,

and has a hardware shutdown feature which reduces cur-

rent consumption to 250μA.

The LTC6404 family is available in a compact 3mm

× 3mm

16-pin leadless QFN package and operates over a –40°C

to 125°C temperature range.
