ADR3650 Datasheet | Analog Devices

FEATURES - Maximum temperature coefficient - 3 ppm/°C (B grade) - 6 ppm/°C (A grade) - Output current capacity (typical): 70 m A sourcing and 20 m A sinking - Low quiescent current: 65 µA - Low shutdown current: 1.5 μA - Output voltage noise (0.1 Hz to 10 Hz): 3 ppm p-p - Maximum initial output voltage error - ±0.04% (B grade) - ±0.08% (A grade) - Operating temperature range: - 40°C to +125°C - Maximum input voltage: 16 V - Low dropout voltage - 0.25 V for the ADR3625 - 0.15 V for the ADR3630 and ADR3650 - 1.8 V logic patible - 8-Lead MSOP package APPLICATIONS - Precision power supplies - Portable instrumentation - Process transmitters - Remote sensors - Medical instrumentation - Auto battery monitors GENERAL DESCRIPTION The ADR3625ADR3630ADR3650 are low power, high precision voltage references that feature a maximum temperature coefficient of 3 ppm/°C for the B grade in an 8-lead MSOP. Capable of sourcing up to 70 m A, the ADR3625ADR3630ADR3650 are an exceptional replacement to standard low dropout (LDO) regulators. For high accuracy, the output voltage and temperature coefficient are trimmed during production using the Analog Devices, Inc., proprietary Digi Trim® technology. The low thermal hysteresis (7 ppm) and low long-term drift (160 ppm at 3500 Hr) improve system lifetime accuracy. A minimum load capacitance of 0.1 μF is required for operation. The ADR3625ADR3630ADR3650 is specified over the - 40°C to +125°C operating temperature range. PIN CONFIGURATION Figure 1. 8-Lead MSOP Pin Configuration Table 1.
