ADC1140

The ADC1140 is a kind of low cost 16-bit sucessive approximation A/D converter that has fast, 35sec conversion time. It is packaged into a small, 2*2*0.4 inch package. This unit will accept an analog input signal either unipolar from 0 to +10 V and/or bipolar from +5 to ±10 V. It is ideal for applications in robtics, process control and selsmic data acquisition, and precision instrumentation.

There are some features of ADC1140 as follows: (1)low cost-small size; (2)16-bit resolution; (3)35 sec conversion time; (4)high stability; (5)low power consumption; (6)CMOS/TTL compatible.

The following is about the specifications (typical @ +25, ±VS=±10 V, VCC=+5 V, Vref=+10.0 V) of ADC1140: (1)resolution: 16 bits; (2)conversion time: 35 sec; (3)differential nonlinearity: ±2 ppm/; (4)gain: ±12 ppm/ max with internal reference and ±4 ppm/ max without internal reference ; (5)unipolar offset: ±30V/ max; (6)bipolar offset: ±7 ppm/ max; (7)operating temperature range: -25 to 85; (8)storage temperature: -55 to 85.
