GENERAL DESCRIPTION

The LND2907HT is a 10-bit Successive Approximation

which is designed to operate from a single-ended

supply of 3.3V and can withstand temperatures up to

200

The LND2907HT provides a front-end interface for high

temperature sensor applications including LVDTs and

Resolvers.

The LND2907HT is built using a temperature insensitive

Digital-to-Analog Converter (DAC), Comparator,

Successive Approximation Register (SAR) and a

Sample and Hold circuit.

The analog input range to the SAR ADC can vary from

mode, powering up only for the conversions. This

process of conversion is controlled by an external

command than comes from the processor and this

results in a lot of power saving.

All the bias voltages required for proper functioning of

various internal components are generated inside the

chip which eliminates the use of external voltage

references.

The LND2907HT provides a serial interface which is

compatible with SPI and hence makes it a good choice

of ADC for many applications.

The LND2907HT is available in a 14-pin DIP package,

and is specified over the temperature range of 27

200

to V

. The ADC normally remains in a shutdown
