EasySMU: I2C Address Translator Demonstration and a Simple Multi-Channel Source Measurement Unit

LTC4316: Single I2C/SMBus Address Translator
LT1970A: Power Op Amp with Adjustable Precision Current Limit
LT5400:  Quad Matched Resistor Network
LTC2655: Quad I2C 16-/12-Bit Rail-to-Rail DACs with 10ppm/°C Max Reference
LTC3265: Low Noise Dual Supply with Boost and Inverting Charge Pumps
LTC2051: Dual Zero-Drift Operational Amplifier
LT3010:  50mA, 3V to 80V Low Dropout Micropower Linear Regulator
LT1991:  Precision, 100µA Gain Selectable Amplifier
LTC6655: 0.25ppm Noise, Low Drift Precision Reference
LTC2485: 24-Bit ΔΣ ADC with Easy Drive Input Current Cancellation and I2C Interface

EasySMU is a single-channel ±12V/40mA programmable-voltage/programmable-current
source with accurate voltage/current measurement capability. The LTC4316 I2C
Address Translator enables up to eight independent EasySMUs to be controlled
by a single I2C master.

In this demonstration, each EasySMU board contains four I2C slaves and the
associated components to implement a single-channel ±12V/40mA programmable-
voltage/programmable-current source. The LTC4316 translates the I2C addresses
of each EasySMU to a unique set of addresses, enabling up to eight EasySMU
boards to be stacked on a single Linduino (I2C master). In this form, it
resembles a multi-channel automated test system. Alternatively, an optional
touchscreen allows the user to interactively control up to four channels,
forming a compact multi-channel programmable-voltage/programmable-current
bench source for lab testing, powered from a single 12V AC wall adapter.

The primary purpose of the EasySMU is to demonstrate the LTC4316 I2C Address
Translator. The programmable-voltage/programmable-current source and meter
also provide a convenient demonstration of the associated components: LT1970A,
LT5400-3, LTC2655-H, LTC3265, LTC2051, LT3010, LT1991, LTC6655, and LTC2485.
While the EasySMU is not designed to demonstrate the ultimate performance that
can be obtained from each of those components, the EasySMU does provide
impressive results from a reasonably simple circuit.
