ADC Voltage Reference Buffer Optimization Reference Design for High Performance DAQ Systems
The TIDA-01055 reference design for high performance DAQ Systems optimizes the ADC reference buffer to improve SNR performance and reduce power consumption with the TI OPA837 high-speed op amp. This device is used in a composite buffer configuration and provides a 22% power improvement over traditional op amps. Voltage reference sources with an integrated buffer often lack the drive strength required to achieve optimal performance in a high-channel count systems.

Non-isolated power architecture with diagnostics reference design for protection relay modules
This reference design showcases non-isolated power supply architectures for protection relays with analog input/output and communication modules generated from 5-: 12-: or 24-V DC input. To generate the power supplies the design uses DC/DC converters with an integrated FET: a power module with an integrated inductor for size- and design-time-constrained applications: a HotRod™ package type for applications requiring low EMI and linear regulators (LDOs) for low ripple. Protections include a flat clamp TVS for input transient protection: an eFuse with configurable load current for overload protection and an ideal diode controller for input reversal protection. Additional features include an auto-switching power MUX: an analog temperature sensor: an input OK indication: a “no load” detection and a voltage supervisor.

Reference Design Maximizing Signal Dynamic Range for True 10 Vpp Differential Input to 20 bit ADC
This reference design is designed for high performance data acquisition(DAQ) systems to improve the dynamic range of 20 bit differential input ADCs. Many DAQ systems require the measurement capability at a wide FSR (Full Scale Range) in order to obtain sufficient signal dynamic range. Many earlier reference designs for SAR ADCs have used the THS4551 FDA (fully differential amplifier). However: the THS4551 is limited to a 5.4V maximum supply which is not sufficient for realizing the true 10Vpp differential output (10V FSR) required to maximize the dynamic range of SAR ADCs with a 5V reference. This reference design explores the benefits of a true 10Vpp differential output by implementing TI's new THS4561 FDA which has a maximum supply of 12.6V. You will see that this design was able to achieve superior performance to the previous design (TIDA-01054) while also lowering overall power consumption.

Multi-Rail Power Reference Design for Eliminating EMI Effects in High Performance DAQ Systems
The TIDA-01054 reference design helps eliminate the performance degrading effects of EMI on Data Acquisition (DAQ) systems greater than 16 bits with the help of the LM53635 buck converter. The buck converter enables the designer to place power solutions close to the signal path without the unwanted noise degradation of EMI while saving board space. This design allows for a system SNR performance of 100.13 dB using a 20-bit: 1-MSPS SAR ADC: which almost matches the 100.14 dB SNR performances when using external power sources.
