10 V precision reference in a SOT-23-6
The MAX6043BAUT10-T is a series voltage reference from Maxim that delivers a fixed 10 V output with a tight ±0.1% initial tolerance and a 25 ppm/°C temperature coefficient. It operates from a 12 V to 40 V input rail and can source up to 10 mA, making it suitable for biasing precision ADCs or DACs in industrial or automotive signal chains. The SOT-23-6 package keeps board area small, and the -40°C to 125°C temperature range covers under-hood and factory-floor environments.
Supply current and output drive
Quiescent supply current is 650 µA typical, which is modest for a precision series reference. The 10 mA output capability can bias multiple op-amp inputs or a small ADC reference input without an external buffer. If your load exceeds 10 mA, you'll need a separate buffer stage — this part is not designed to drive heavy loads.
Sourcing and lifecycle
The MAX6043BAUT10-T is listed as Active with no end-of-life notice. It is RoHS non-compliant per the manufacturer's declaration, so verify your assembly house's exemption policy if you require full RoHS compliance.
