Very-low-noise and programmable very-high-gain DC-voltage amplifier with precision offset trimming
The TS_VA_LNDC_X8 comprises the main function dcamp and its companion dcamptrim.
Overview
The TS_VA_LNDC_X8 comprises the main function dcamp and its companion dcamptrim. The dcamp is a very-low-output-noise-level (604µVRMS max) and 1%-precise programmable very-high-gain (32 selectable gains up to 400V/V) DC-voltage amplifier, with an extra differential input for precision offset trimming by the dual 8-bit one’s-complement-coded DAC dcamptrim.
The dcamp and dcamptrim operate with one supply voltage VDDA4 (4V typical) and one precision reference voltage VREF (2.5V).
The dcamp complies with 2kV electrostatic discharges on its analog terminals VIN, FB_IN and VOUT.
The minimum continuous operation lifetime spans 100000 hours.
