GENERAL DESCRIPTION

The AD680 is a band gap voltage reference that provides a fixed

2.5 V output from inputs between 4.5 V and 36 V. The

GND

OUT

architecture of the AD680 enables the reference to be operated

at a very low quiescent current while still realizing excellent dc

characteristics and noise performance. Trimming of the high

stability thin-film resistors is performed for initial accuracy and

temperature coefficient, resulting in low errors over temperature.

PRODUCT HIGHLIGHTS

1. High Accuracy.

The AD680 band gap reference operates on a very low

quiescent current which rivals that of many 2-terminal

references. This makes the complete, higher accuracy AD680

ideal for use in power-sensitive applications.

The precision dc characteristics of the AD680 make it ideal for

use as a reference for DACs that require an external precision

reference. The device is also ideal for ADCs and, in general, can

offer better performance than the standard on-chip references.

Based upon its low quiescent current, which rivals that of many

incomplete 2-terminal references, the AD680 is recommended

for low power applications, such as hand-held, battery-operated

equipment.

2. Low Errors.

Laser trimming of both initial accuracy and temperature coef-

ficients results in low errors over temperature without the use

of external components. The AD680AN and AD680AR have

a maximum variation of 6.25 mV between −40°C and +85°C.

A temperature output pin is provided on the 8-lead package

versions of the AD680. The temperature output pin provides an

output voltage that varies linearly with temperature and allows

the AD680 to be configured as a temperature transducer while

providing a stable 2.5 V output.

3. Low Noise.

The AD680 noise is low, typically 8 μV p-p from 0.1 Hz to

10 Hz. Spectral density is also low, typically 250 nV/√Hz.

4. Temperature Transducer.

The AD680 is available in five grades. The AD680AN is speci-

fied for operation from −40°C to +85°C, while the AD680JN is

specified for 0°C to 70°C operation. Both the AD680AN and

AD680JN are available in 8-lead PDIP packages. The AD680AR

is specified for operation from −40°C to +85°C, while the

AD680JR is specified for 0°C to 70°C operation. Both are

available in 8-lead SOIC packages. The AD680JT is specified for

0°C to 70°C operation and is available in a 3-pin TO-92

package.

The temperature output pin on the 8-lead package versions

enables the AD680 to be configured as a temperature

transducer.

5. Low Cost.

PDIP packaging provides machine insertability, while SOIC

packaging provides surface-mount capability. TO-92

packaging offers a cost-effective alternative to 2-terminal

references, offering a complete solution in the same package

in which 2-terminal references are usually found.
