- Manufacturer:
- Linear Technology
- Ventron No:
- 3012710-LTC2435-1CGN#PBF
- Description:
- IC ADC DIFF I/REF 20BIT 16-SSOP
- Datasheet:
- LTC2435-1CGN#PBF
Description
The LTC2435/LTC2435-1 are 20-bit differential AΣ analog-to-digital converters with an integrated oscillator, 3ppm INL, and 0.8ppm RMS noise. They use delta-sigma technology and provide single-cycle settling time for multiplexed applications. The LTC2435 can be configured for better than 110dB input differential mode rejection at 50Hz or 60Hz ±2%, or it can be driven by an external oscillator for a user-defined rejection frequency. The LTC2435-1 can be configured for better than 87dB input differential mode rejection over the range of 49Hz to 61.2Hz (50Hz and 60HZ 2% simultaneously). The internal oscillator requires no external frequency setting components.
The converters accept any external differential reference voltage from 0.1V to Vcc for flexible ratiometric and remote sensing measurement configurations. The full-scale differential input range is from -0.5VREF to 0.5VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be independently set anywhere within the GND to Vcc range of the LTC2435/LTC2435-1. The DC common mode input rejection is better than 120dB.
The LTC2435/LTC2435-1 communicate through a flexible 3-wire digital interface which is compatible with SPI and MICROWIRE™ protocols.
