Renesas X60008DIS8-50

Overview

X60008DIS8-50 from Intersil is a precision 5.000V floating-gate analog (FGA™) voltage reference with ±1.0mV initial accuracy, 10ppm/°C temperature coefficient, and ultra-low 500nA supply current. It operates from 5.1V to 9.0V input, delivers 10mA source/sink capability, and targets high-resolution data acquisition in battery-powered industrial and portable systems.

For engineers reviewing the X60008DIS8-50 datasheet, X60008DIS8-50 pinout, X60008DIS8-50 application, or X60008DIS8-50 equivalent, key selection criteria include long-term stability (10ppm/1000hrs), dropout voltage (150mV @ 5mA), output noise (30µVpp, 0.1Hz–10Hz), thermal hysteresis (50ppm), and SOIC-8 packaging for space-constrained PCB layouts.

Technical Context

The X60008DIS8-50 implements Intersil's proprietary Floating Gate Analog (FGA™) technology-distinct from bandgap, buried zener, or XFET™-to achieve sub-1mV initial accuracy and flat temperature drift across –40°C to +85°C. Its CMOS-based output stage enables 10mA bidirectional load current while maintaining ultra-low quiescent current.

It features a buffered reference core with internal charge-trapped floating gate cell, delivering stable 5.000V output without external trimming. The device requires no enable control, has no serial interface, and uses passive output filtering (e.g., 0.001µF) to suppress noise below 40µVpp across 1Hz–1MHz when combined with RC network.

FAQ

What is the absolute maximum input voltage rating for the X60008DIS8-50?

The X60008DIS8-50 has an absolute maximum input voltage of +10V referenced to GND. Exceeding this voltage risks permanent damage. The recommended operating range is 5.1V to 9.0V, and operation above 9.0V is not characterized or guaranteed. Always include input protection (e.g., series resistor + TVS) in designs where transient overvoltage is possible. The X60008DIS8-50 datasheet specifies –0.5V to +10V as the absolute limit on any pin relative to GND.

Does the X60008DIS8-50 require an enable pin or external startup sequencing?

No, the X60008DIS8-50 has no enable pin and requires no external startup sequencing. It powers up automatically when VIN exceeds ~5.1V. Typical turn-on time is 7ms (up to 12ms depending on unit-to-unit supply current variation). System firmware must delay ADC conversions or analog measurements until after this period. The X60008DIS8-50 does not support shutdown mode or digital control-its operation is fully autonomous once powered.

Can the X60008DIS8-50 drive a 10kΩ load directly without output buffer?

Yes, the X60008DIS8-50 can drive a 10kΩ load directly. At 0.5mA load current, its load regulation is specified at 15–50µV/mA, resulting in <25µV shift-well within its ±1.0mV initial accuracy. For loads ≤10mA, no buffer is needed. However, for capacitive loads >0.001µF, the recommended RC filter (2kΩ + 10µF) must be used to maintain stability and noise performance. The X60008DIS8-50's 10mA source/sink capability covers most precision analog interface needs.

What is the purpose of the four DNC pins on the X60008DIS8-50 SOIC package?

The four DNC (Do Not Connect) pins on the X60008DIS8-50-pins 2, 4, 5, and 6-are internally connected to substrate or isolation structures and must remain electrically floating. Soldering, routing traces, or applying solder mask to these pins may cause parametric shifts or reliability issues. The X60008DIS8-50 datasheet explicitly prohibits connections to these terminals, and PCB layout must exclude pads, vias, or copper near them per MDP0027 mechanical drawing.

How does the X60008DIS8-50 achieve 10ppm/1000hrs long-term stability?

The X60008DIS8-50 achieves 10ppm/1000hrs long-term stability through Intersil's Floating Gate Analog (FGA™) process, which traps charge on an isolated polysilicon gate with extremely low leakage (<1fA/cm²). This minimizes drift caused by charge migration-a dominant failure mechanism in conventional bandgap references. Accelerated life testing under JEDEC JESD22-A108 confirms this spec. The X60008DIS8-50's stability is intrinsic to its silicon structure, not dependent on external components or board layout.
