com LTC6404 600MHz, Low Noise, High Precision Fully Differential Input/Output Ampliﬁer/Driver DESCRIPTION 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 current 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.
