EUSB to MAX1236 Kit
EID's universal serial bus (EUSB)
to MAX1236 kit (serial
12-bits ADC) is an educational electronics kit
that allows you to connect your personal computer (PC) universal
serial port to up to 4 analog to digital input. The kit is based on Cypress
integrated circuit (IC), the CY7C63001.
Note:
The CY7C63001 IC is
Universal Serial Bus (USB) RISC type Micro-controller.
It conforms to USB 1.5 Mbps specification, version 1.1.

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).
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). whoever we chose to read the device input 4
times per second.
Connect
the board to your PC E-USB port, few lines of code and you have high performance
12bit 4 channels ADC.

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.
No
need for external Power supply! The board is powered directly
from your PC.
Kit
mounting
This
kit includes on board
pre-installed free
EUSB firmware!
This
unique kit design provides you with the ability to wire your wires
easily via front mounted terminal blocks (5). You will be able to
measure 1 single-ended voltages directly
from the PC.

series) with Caps (use as filters) option.
Please
note: Plastic enclosure
and caps are sold
separately
(for demonstration only).
