8-SOIC footprint and what it connects to
The MAX6143AASA50+: The 8-pin SOIC body keeps the thermal path short to the copper pour, which matters when the reference is sourcing 30 mA continuously.
What ±0.06% initial accuracy and 3 ppm/°C drift mean for the ADC chain
The ±0.06% initial tolerance sets the absolute voltage error at 25 °C — for a 5 V output, that is ±3 mV before any temperature or load effects. Together they define the reference's contribution to the system's total unadjusted error budget. The low-frequency 1/f noise dominates in precision DC measurements; the wideband figure matters when the reference is sampled at kHz rates. A 16-bit ADC with a 5 V reference has a 76 µV LSB — the reference noise floor sits well below one LSB, so it does not limit the converter's effective resolution.
Input range and output current — the supply and load envelope
The 30 mA output current is enough to bias multiple ADC reference inputs or a precision DAC's reference buffer — but not a power-hungry load like a heater or solenoid. The 700 µA supply current is the reference's own draw, not the load current; the total power dissipation is the sum of (Vin - Vout) × Iout plus the quiescent current.
Active production and compliance paperwork
Analog Devices lists the MAX6143AASA50+ as Active and ROHS3 Compliant. The Tube package is the standard delivery format for prototype and low-volume builds; reel options are available through the distributor's ordering system.
