LT3999

• Fully Isolated PMOD-to-FMC interposer board
• Software programmable bipolar input ranges (±1.1 V to ±11.0 V)
  
  • Allows single-ended and differential signals
• GΩ input impedance allows direct interface with sensors
• On-board 5 V reference and buffer
• Complete power management solution
• SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface
• PC software for control and data analysis of time and frequency domain

The ADSKPMB10-EV-FMCZ signal chain kit is a two-board solution, which consists of a Precision Medium Bandwidth Data Acquisition Solution on a PMOD form factor and a Fully Isolated PMOD-to-FMC interposer board.

The Precision Medium Bandwidth Data Acquisition Solution features a discrete programmable gain instrumentation amplifier (PGIA) that was built using a 30V, High Speed, Low Noise, Low Bias Current, JFET Operational Amplifier, the ADA4627-1, a Precision Quad Matched Resistor Network, the LT5400, a Low Capacitance, 4-Channel, ±15 V/+12 V iCMOS^™ Multiplexer, the ADG1209 and the internal Fully Differential Amplifier (FDA) ADC driver of the ADAQ4003. The PGIA in thru front-end offers high input impedance that allows direct interface with a variety of sensors. A programmable gain is often needed to adapt the circuit to different input signal amplitudes—unipolar or bipolar and single-ended or differential with varying common-mode voltages. The PGIA works with the ADAQ4003, an 18-Bit, 2 MSPS, µModule^® Data Acquisition Solution.

The Fully Isolated PMOD-to-FMC interposer board was designed using a Low Noise, 1A, 1MHz Push-Pull DC/DC Driver with Duty Cycle Control, the LT3999, a Robust 3.0kVrms Digital Isolators w/ Fail-Safe for the SPI lines and PGIA gain control pins, the ADuM152N and the ADuM120N, and a Low noise and ultra-low noise LDO regulators the ADP7105 and the ADP150N respectively.

The DC2049A demonstrates how a power supply regulates two output voltage by using the LT3999 and low dropout (LDO) regulators.

The LT3999 is a monolithic push-pull DC/DC driver which features a wide input range and small external passive components.

The LT3999 has duty circle control for ΔV_IN compensation, which allows for a wide input voltage range and low LDO losses.
