TIPD144 Comparator with Hysteresis Reference Design | TI.com
TIPD144: This TI Verified Design implements a comparator with hysteresis. Comparators are used to differentiate between two different signal levels. For example, a comparator may differentiate between an over temperature and normal temperature condition. Noise or signal variation at the comparison threshold will cause multiple transitions. Hysteresis sets an upper and lower threshold to eliminate the multiple transitions caused by noise.
TIPD130 Dual Polarity High-Voltage Differential Input Interface for Low-Voltage Comparators Reference Design | TI.com
TIPD130: This TI Verified Design provides the theory, component selection, simulation, schematic, PCB layout, BOM, and measured performance for a dual polarity (bipolar), high-voltage differential input interface for low-voltage comparators. The design allows a comparator such as the TLV3201 to operate with a single +3.3 V supply and to compare two input voltages that not only exceed its normal input range, but can be of either (±) polarity. The design takes into account all the comparator and passive component errors and results in <10 mV, of dc input error. Worst-case analyses techniques are provided to determine the dc error contributed by limited resistor tolerance, for the resistors used in the comparator input networks.

TIDA-00448 Flexible High Current IGBT Gate Driver with Reinforced Digital Isolator Reference Design | TI.com
TIDA-00448: The TIDA-00448 reference design is an isolated IGBT gate driver with bipolar gate voltages intended for driving high power IGBT’s requiring high peak gate current up to 40 A. TI’s NexFET power blocks which scales in this range, with same package, enables single design to be used for multiple drive platforms with different power ratings. A Digital isolator is used to achieve reinforced isolation with transient surge rating of 8kV and 50kV CMTI. The design incorporates DESAT protection using a fast transient response comparator. The DESAT detection threshold and the soft turn-off time are configurable. The design can interface with PWMs from 3.3 V and 5 V MCUs along with fault, reset and UVLO feedbacks.

TIDA-00929 Spectrum Analyzer Signal Conditioning and Processing for Capturing Arc Signatures Reference Design | TI.com
TIDA-00929: The TIDA-00929 TI design demonstrates bandwidth optimized analog front end (AFE) and real-time FIR implementation using low power to capture broadband frequency spectrum in any waveform. Operational amplifier in each signal path is chosen based on the gain, signal bandwidth, low noise, close to the rail swing requirements while consuming low power. The waveform is processed in real-time both in frequency and time domain using mixed signal ultra low power microprocessor with built in vector math engine.
