NTE2050

The NTE2050 and NTE2051 are high performance, low power 31/2 digit A/D converters containing all the necessary active devices on a single CMOS IC. Included are seven segment decoders, display drivers, reference and a clock. The NTE2051 is designed to interface with a liquid crystal display (LCD) and includes a backplane drive; the NTE2050 will directly drive an instrumentsize light emitting diode (LED) display.

The NTE2050 and NTE2051 bring together an unprecedented combination of high accuracy, versatility, and true economy. High accuracy like autozero to less than 10V, zero drift of less than 1V/°C, input bias current of 10pA max., and rollover error of less than one count. The versatility of true differential input and reference of NTE2050 is useful in all systems, but gives the designer an uncommon advantage when measuring load cells, strain gauges and other bridgetype transducers. And, finally, the true economy of single power supply operation (NTE2051), enabling a high performance panel meter to be built with the addition of only 7 passive components and a display.
