PRODUCT DESCRIPTION

The AD780 is a pin compatible performance upgrade for the

LT1019(A)–2.5 and the AD680. The latter is targeted toward

low power applications.

The AD780 is an ultrahigh precision band gap reference voltage

that provides a 2.5 V or 3.0 V output from inputs between 4.0 V

and 36 V. Low initial error and temperature drift combined with

low output noise and the ability to drive any value of

capacitance make the AD780 the ideal choice for enhancing the

performance of high resolution ADCs and DACs, and for any

general-purpose precision reference application. A unique low

headroom design facilitates a 3.0 V output from a 5.0 V 10%

input, providing a 20% boost to the dynamic range of an ADC

over performance with existing 2.5 V references.

The AD780 is available in three grades in PDIP and SOIC

packages. The AD780AN, AD780AR, AD780BN, AD780BR,

and AD780CR are specified for operation from −40°C to

+85°C.

PRODUCT HIGHLIGHTS

1. The AD780 provides a pin programmable 2.5 V or 3.0 V

output from a 4 V to 36 V input.

The AD780 can be used to source or sink up to 10 mA, and can

be used in series or shunt mode, thus allowing positive or

negative output voltages without external components. This

makes it suitable for virtually any high performance reference

application. Unlike some competing references, the AD780 has

no region of possible instability. The part is stable under all load

conditions when a 1 µF bypass capacitor is used on the supply.

2. Laser trimming of both initial accuracy and temperature

coefficients results in low errors over temperature without

the use of external components. The AD780BN has a

maximum variation of 0.9 mV from −40°C to +85°C.

3. For applications that require even higher accuracy, an

optional fine-trim connection is provided.

4. The AD780 noise is extremely low, typically 4 mV p-p from

0.1 Hz to 10 Hz and a wideband spectral noise density of

A temperature output pin on the AD780 provides an output

voltage that varies linearly with temperature, allowing the part

to be configured as a temperature transducer while providing a

stable 2.5 V or 3.0 V output.

typically 100 nV/√ . This can be further reduced, if

desired, by using two external capacitors.

5. The temperature output pin enables the AD780 to be

configured as a temperature transducer while providing a

stable output reference.
