HI7191IPZ - Renesas Electronics

Description: The Intersil HI7191 is a monolithic instrumentation, sigma delta A/D converter which operates from ±5V supplies. Both the signal and reference inputs are fully differential for maximum flexibility and performance. An internal Programmable Gain Instrumentation Amplifier (PGIA) provides input gains from 1 to 128 eliminating the need for external pre-amplifiers. The on-demand converter auto-calibrate function is capable of removing offset and gain errors existing in external and internal circuitry. The on-boar

HI7191IPZ Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the application note AN1463, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The HI7191IPZ has a high current output capability, but it requires proper thermal management and PCB design to handle the heat generated. Use a heat sink, thermal vias, and a thick copper layer on the PCB to dissipate heat effectively.
  • Although the datasheet specifies a minimum input voltage of 4.5V, Renesas recommends an input voltage range of 5V ±10% for optimal performance and to ensure that the device operates within its specified parameters.
  • To configure the HI7191IPZ for low-power operation, use the Power-Down (PD) pin to put the device in a low-power state. Additionally, adjust the clock frequency and output current to minimize power consumption.
  • Although the datasheet specifies a maximum clock frequency of 100 MHz, Renesas recommends a maximum clock frequency of 80 MHz to ensure reliable operation and minimize jitter.
