Utilizing the MAX1236 (Maxim Inc, www.maxim-ic.com ) surface mount (SMT) integrated circuit (IC). 4-channels single-ended or 2-differential-channels 12-bits Analog to digital converter (ADC) with built-in 4.096V reference voltage. The device controlled via 2 wires Clock and Data (I2C protocol). This kit is ideal for portable and battery-powered applications.

 

   

 

Model A includes input filters.

 

   

 

Model B

 

The MAX1236 is a low-power 12-bit, multi-channel analog-to-digital converters (ADCs) feature internal track/hold (T/H), internal 4.096V reference voltage, clock, and an I2C-compatible -- 2-wire serial interface (clock and data). The device operates from a single supply voltage of 4.5V to 5.5V and require only 670µA at the maximum sampling rate of 94.4ksps. Supply current falls below 230µA for sampling rates under 46ksps. Automatic shutdown -- powers down between conversions, reducing supply current to less than 1µA at low throughput rates. The MAX1236 has four analog input channels. The fully differential analog inputs are software configurable for uni-polar or bi-polar, and single-ended or differential operation. 

 

The full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to VCC. As mentioned above The MAX1236 feature a 4.096V internal reference. 

 

The MAX1236 is available in an 8-pin µMAX package. The MAX1236 is guaranteed over the extended temperature range (-40°C to +85°C). For pin-compatible 10-bit parts, refer to the MAX1136-MAX1139 data sheet. For pin-compatible 8-bit parts, refer to the MAX1036-MAX1039 data sheet. 

 

The device is also support high-speed I2C-compatible serial Interface, both, 400kHz fast-mode  and 1.7MHz high-speed mode. The device has excellent dynamic performance (SINAD > 70dB), and excellent DC accuracy (INL = ±1LSB).

 

Connect the board to your PC parallel port or USB port via 4 wires (5V, GND, Clock, Data), few lines of code and you have high performance 12bit 4 channels ADC.

 

 

Max1236 Block Diagram

 

The Max1236 has internal reference voltage of 4.096V  since the IC conversion is via 12bit ( 2^12 = 4096). you will be able to measure voltage increments of 1mV {V_Ref / (2^12) = 4.096V / 4096 = 1mV}.

 

Connect it to one of our OP-AMP boards set your input gain and build your won PC base voltmeter.
