PRODUCT DE SCRIPT ION
T he AD680 is a bandgap voltage reference which provides a
fixed 2.5 V output from inputs between 4.5 V and 36 V. T he
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. T rimming of the high
stability thin-film resistors is performed for initial accuracy and
temperature coefficient, resulting in low errors over temperature.
T he precision dc characteristics of the AD680 make it ideal for
use as a reference for D/A converters which require an external
precision reference. T he device is also ideal for A/D converters
and, in general, can offer better performance than the standard
on-chip references.
Based upon the low quiescent current of the AD680, which
rivals that of many incomplete two-terminal references, the
AD680 is recommended for low power applications such as
hand-held battery equipment.
A temperature output pin is provided on the 8-pin package ver-
sions of the AD680. T he 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.
T he AD680 is available in five grades. T he 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-pin plastic DIP packages. T he
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 an 8-pin Small Outline IC (SOIC) pack-
age. T he AD680JT is specified for 0
°
C to +70
°
C operation and
is available in a 3-pin T O-92 package.
*Protected by U.S. Patent Nos. 4,902,959; 4,250,445 and 4,857,862.
PRODUCT HIGHLIGHT S
1. T he AD680 bandgap reference operates on a very low quies-
cent current which rivals that of many two-terminal refer-
ences. T his makes the complete, higher accuracy AD680
ideal for use in power sensitive applications.
2. Laser trimming of both initial accuracy and temperature
coefficients results in low errors over temperature without the
use of external components. T he AD680AN and AD680AR
have a maximum variation of 6.25 mV between –40
°
C and
+85
°
C.
3. T he AD680 noise is low, typically 8
μ
V p-p from 0.1 Hz to
10 Hz. Spectral density is also low, typically 250 nV/
√
Hz
.
4. T he temperature output pin on the 8-pin package versions
enables the AD680 to be configured as a temperature trans-
ducer.
5. Plastic DIP packaging provides machine insertability, while
SOIC packaging provides surface mount capability. T O-92
packaging offers a cost effective alternative to two-terminal
references, offering a complete solution in the same package
in which two-terminal references are usually found.
