This reference design implements and measures a complete 120MHz high-bandwidth optical front-end consisting of a high-speed transimpedance amplifier, a fully differential amplifier, and a high-speed 14-bit 160MSPS ADC with JESD204B interface. The design provides hardware and software to evaluate the system's response to high-speed optical pulses generated by the included laser driver and diode, suitable for applications with optical time domain reflectometry (OTDR).
This analog front end (AFE) design shows how to connect two or more Σ-Δ ADCs for simultaneous sampling and how to expand the number of input channels to provide maximum flexibility. Precision current measurement is achieved by connecting the AFE to a current transformer (CT) and a Rogowski coil. Likewise, accurate voltage measurements are achieved using resistive voltage dividers without and with isolation amplifiers. The AFE can be configured to measure unipolar or bipolar inputs. The required power is provided onboard. Additionally, diagnostics can be integrated into one design, as shown in TIDA-00810.

This reference design is an automotive-qualified isolated gate driver solution that drives silicon carbide (SiC) MOSFETs in a half-bridge configuration. This design provides two push-pull bias supplies for dual-channel isolated gate drivers, each providing +15V and –4V output voltages and 1W output power. The gate driver is capable of 4A peak source current and 6A peak sink current. The driver implements reinforced isolation and can withstand 8kV peak isolation voltage and 5.7kV RMS isolation voltage as well as common-mode transient immunity (CMTI) of over 100V/ns. This reference design includes a two-stage shutdown circuit that protects the MOSFET against voltage overshoot during short circuit conditions. DESAT detection threshold and second stage shutdown delay time are configurable. This design uses an ISO7721-Q1 digital isolator to connect the fault and reset signals. The overall design adopts a compact double-layer PCB board of 40mm × 40mm.
