It is built for precision analog chains — ADC/DAC reference, sensor excitation, or power-supply biasing — where initial accuracy of ±0.05% and temperature drift of 10 ppm/°C keep the system error budget tight. The dual-output architecture means one part replaces two single references, saving board area and improving thermal tracking between the two channels. ## Sourcing and lifecycle The LT6658AHMSE-1.8#PBF carries an Active product status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. The dual-output, high-drive feature set means there is no direct pin-compatible second-source; the ADR44x family from ADI is a functional alternative but offers single output at lower drive current.","metaTitle":"LT6658AHMSE-1.8#PBF Voltage Reference, ±0.05%, 20mA","metaDescription":"LT6658AHMSE-1.8#PBF precision dual series reference: 1.8V fixed output, ±0.05% tolerance, 20mA drive, 1ppm p-p noise.
