Reference VoltHive - +/- 4.096V and +/- 2.048V
Anabit’s Reference VoltHive is an open-source, voltage reference module for data converters, mixed-signal designs, and any use case that demands accurate, ultra-stable rails. It provides four precision, buffered references—+4.096 V, +2.048 V, –4.096 V, and –2.048 V—so you can validate, calibrate, and bias unipolar or bipolar ADC/DAC systems with confidence. Each output is buffered to deliver a low-impedance, interference-resistant source that stays rock-solid when you switch ranges or load your circuit.
Beyond references, VoltHive simplifies bipolar power needs by supplying –6.2 V and –5 V auxiliary rails to power op-amp stages or other negative-supply blocks. The result is a compact, dependable bench companion or design module that tightens measurement repeatability, and gives your precision analog designs a clean foundation.
Product Features:
- delivers four precision voltage references at +/- 4.096 and +/- 2.048V as well as low power negative DC voltage supplies at -6.2V (switched based) and -5V (linear based)
- Powered from a single DC supply at 5V, can run off 3.3V supply if you only want to use +/- 2.048V references, the -6.2V supply, or the -5V supply
Reference VoltHive example use cases:
- ADC and DAC circuit design and testing
- Op amp circuit biasing
- Servo drive control module
- Electricity meter, Servo drive control, Circuit breaker
- Clinical digital thermometer
- Lab & field instrumentation
- Battery test instruments

Product features
--> Precision Reference Voltage Outputs:
4.096V, -4.096V, 2.048V, -2.048V
--> Wide current range per voltage reference output (20mA to -20mA), could even be used as an ultra low noise power in low power circuits
--> Negative power supply voltage outputs: -6.2V switch based regulator and -5V low noise linear regulator based
Specifications
Specifications
--> Accuracy of the 4.096V and 2.048V outputs is 0.025% and the accuracy of the -4.096V and -2.048V outputs is 0.04%
--> Max Current Source and sink per reference output: 20mA to -20mA
--> -5V linear supply output accuracy is 1% and supports a max current of 100mA
--> -6.2V supply can support a max current of 200mA, but that current is shared with the -5V supply so be sure the current output of both -6.2V and -5V supply is < 200mA
--> Small form factor at 44.5mm x 29.5mm. 2.54mm spaced through holes for easy use with a bread board. Utilize the three 3mm holes to support mounting.
--> If all outputs, voltage references and negative supplies, are being used at the maximum rated current then the 5V input could draw as much as 350mA. If you are just using the references at 5mA or less then 5V input current will be < 50mA
