  • 16 fixed output voltage options with tracking: 0.75 V to 3.3 V
  • Low output noise: 40 μV rms
  • High PSRR: 72 dB @ 1 kHz
  • Stable with small 2.2 μF ceramic output capacitor
  • See data sheet for additional features

The ADP1712 / ADP1713 / ADP1714, available in a tiny, 5-lead TSOT package, are low dropout linear regulators that operate from 2.5 V to 5.5 V and provide up to 300 mA of output current. The low 170 mV dropout voltage at a 300 mA load improves efficiency and allows operation over a wide input voltage range. Using a novel scaling architecture, ground current is a very low 75 μA when driving a 100 μA load, making the ADP1712/ ADP1713/ADP1714 ideal for battery-operated portable equipment.

The ADP1712 / ADP1713 / ADP1714 are available in 16 fixed output voltage options. The ADP1712 is also available in an adjustable version, which allows output voltages that range from 0.8 V to 5 V via an external divider. The ADP1712 fixed version allows an external capacitor to be connected to program the soft-start time. The ADP1713 allows a reference bypass capacitor to be connected, which reduces output voltage noise and improves power supply rejection. The ADP1714 includes a tracking feature, which allows the output to follow an external voltage rail or reference.

The ADP1712/ADP1713/ADP1714 are optimized for stable operation with small 2.2 μF ceramic output capacitors, allowing good transient performance while occupying minimal board space. An enable pin controls the output voltage on all devices, and an undervoltage lockout circuit disables the regulator if IN drops below a minimum threshold. The parts also have short circuit protection and thermal overload protection, which prevent damage to the devices in adverse conditions.

Features and Benefits

  • Provides two channels of ADC and two channels of DAC with full synchronization capabilities
  • FMC-compatible form factor
  • Powered from single FMC connector

Product Details

The AD-FMCDAQ3-EBZ module is comprised of the AD9680 dual, 14-bit, 1.25 GSPS, JESD204B ADC, the AD9152 dual, 16-bit, 2.5 GSPS, JESD204B DAC, the AD9528 clock, and power management components. It is clocked by an internally generated carrier platform via the FMC connector, comprising a completely self-contained data acquisition and signal synthesis prototyping platform. In an FMC footprint (84 mm × 69 mm), the module’s combination of wideband data conversion, clocking, and power closely approximates real-world hardware and software for system prototyping and design, with no compromise in signal chain performance.


Applications

  • Electronic test and measurement equipment
  • General-purpose software radios
  • Radar systems
  • Ultra-wideband satellite receivers
  • Signals intelligence (SIGINT)
  • Point to point communication systems
  • DOCSIS 3.0 CMTS and HFC networks
  • Multiple input/multiple output (MIMO) radios
  • Automated test equipment
