ADI ADR3540WARMZ-R7

The ADR3525W, ADR3530W, ADR3533W, ADR3540W, and ADR3550W are low cost, low power, high precision CMOS voltage references, featuring a maximum temperature coefficient (TC) of 5 ppm/°C (B grade), 8 ppm/°C (A grade), low operating current, and low output noise in an 8-lead MSOP package. The low output voltage hysteresis and low long-term output voltage drift improve lifetime system accuracy. These CMOS references are available in five output voltages, all of which are specified over the automotive temperature range of -40°C to +125°C.

• Maximum temperature coefficient: 5 ppm/°C (B grade)
• Low long-term drift (LTD): 30 ppm (initial 1 khr typical)
• Initial output voltage error: ±0.1% (maximum)
• Operating temperature range: -40°C to +125°C
• Output current: +10 mA source -3 mA sink
• Low quiescent current: 100 μA (maximum)
• Low dropout voltage: 250 mV at 2 mA
• Output voltage noise (0.1 Hz to 10 Hz): 29 μV p-p at 4.096 V (typical)
