The LTC6406 is a very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single supply operation. The LTC6406 input common mode range is rail-to-rail, while the output common mode voltage is independently adjustable by applying a voltage on the VOCM pin. This makes the LTC6406 ideal for level shifting signals with a wide common mode range for driving 12-bit to 16-bit single supply, differential input ADCs.
A 3GHz gain-bandwidth product results in 70dB linearity for 50MHz input signals. The LTC6406 is unity gain stable and the closed-loop bandwidth extends from DC to 800MHz. The output voltage swing extends from near-ground to 2V, to be compatible with a wide range of ADC converter input requirements. The LTC6406 draws only 18mA, and has a hardware shutdown feature which reduces current consumption to 300µA.
The LTC6406 is available in a compact 3mm x 3mm 16-pin leadless QFN package as well as an 8-lead MSOP package, and operates over a –40°C to 85°C temperature range.
