ADR3512 TOP VIEW (Not to Scale) Figure 1. 8-Lead MSOP (RM-8 Suffix) GENERAL DESCRIPTION The ADR3512 is a low cost, low power, high precision CMOS voltage reference, featuring a maximum temperature coefficient (TC) of 4 ppm/°C (C grade, −40°C to +85°C), low operating current, and low output noise in an 8-lead MSOP package. For high accuracy, the output voltage and temperature coefficient are trimmed digitally during final assembly using the Analog Devices, Inc., patented DigiTrim® technology.1 The low output voltage hysteresis and low long-term output voltage drift improve lifetime system accuracy. This CMOS reference is specified over the automotive temperature range of −40°C to +125°C. Table 1. Selection Guide Model Output Voltage (V) Input Voltage Range (V) ADR3512WCRMZ-R7 1.200 2.3 to 5.5 1 At least U.S. Patent No. 6,696,894 covers this technology. |
