TL431AILPG

TO-92-3

On Semiconductor

The TL431, A, B integrated circuits are three-terminal programmable shunt regulator diodes. These monolithic IC voltage references operate as a low temperature coefficient zener which is programmable from Vref to 36 V with two external resistors. These devices exhibit a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 W. The characteristics of these references make them excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5 V reference makes it convenient to obtain a stable reference from 5.0 V logic supplies, and since the TL431, A, B operates as a shunt regulator, it can be used as either a positive or negative voltage reference.

AD586KRZ

SOP-8

Analog Devices

The AD586 represents a major advance in the state-of-the-art in monolithic voltage references. Using a proprietary ion-implanted buried Zener diode and laser wafer trimming of high stability thin-film resistors, the AD586 provides outstanding performance at low cost. The AD586 offers much higher performance than most other 5 V references. Because the AD586 uses an industry standard pinout, many systems can be upgraded instantly with the AD586. The buried Zener approach to reference design provides lower noise and drift than bandgap voltage references. The AD586 offers a noise reduction pin which can be used to further reduce the noise level generated by the buried Zener. The AD586 is recommended for use as a reference for 8-, 10-, 12-, 14- or 16-bit D/A converters which require an external precision reference. The device is also ideal for successive approximation or integrating A/D converters with up to 14 bits of accuracy and, in general, can offer better performance than the standard on-chip references. The AD586J, K, L and M are specified for operation from 0°C to +70°C, the AD586A and B are specified for -40°C to +85°C operation, and the AD586S and T are specified for -55°C to +125°C operation. The AD586J, K, L and M are available in an 8-pin plastic DIP. The AD586J, K, L, A and B are available in an 8-pin plastic surface mount small outline (SO) package. The AD586J, K, L, S and T are available in an 8-pin cerdip package.

The AD587 represents a major advance in state-of-the-art monolithic voltage references. Using a proprietary ion-implanted buried Zener diode and laser wafer trimming of high stability thin-film resistors, the AD587 provides outstanding performance at low cost. The AD587 offers much higher performance than most other 10 V references. Because the AD587 uses an industry-standard pinout, many systems can be upgraded instantly with the AD587. The buried Zener approach to reference design provides lower noise and drift than band gap voltage references. The AD587 offers a noise-reduction pin that can be used to further reduce the noise level generated by the buried Zener. The AD587 is recommended for use as a reference for 8-bit, 10-bit, 12-bit, 14-bit, or 16-bit DACs that require an external precision reference. The device is also ideal for successive approximation or integrating ADCs with up to 14 bits of accuracy. In general, it offers better performance than standard on-chip references. The AD587J and AD587K are specified for operation from 0°C to 70°C, and the AD587U is specified for operation from ?55°C to +125°C. The AD587JQ and AD587UQ models are available in 8-lead CERDIP. Other models are available in an 8-lead SOIC package for surface-mount applications, or in an 8-lead PDIP. Product Highlights Laser trimming of both initial accuracy and temperature coefficients. This laser trimming results in very low errors over temperature without the use of external components. The AD587U guarantees ±14 mV maximum total error between ?55°C and +125°C. Optional fine trim connection. This connection is designed for applications requiring higher precision. Instant upgrade of any system using an industry-standard pinout 10 V reference. Very low output noise. AD587 output noise is typically 4 μV p-p. A noise-reduction pin is provided for additional noise filtering using an external capacitor. MIL-STD-883-compliant versions available. Refer to the Analog Devices Military/Aerospace Reference Manual for detailed specifications.
