LTC2413 24-Bit No Latency ADC, with Simultaneous 50Hz/60Hz Rejection Fea T Descrip T n Simultaneous 50Hz/60Hz Rejection The LTC 2413 is a 2.7V to 5.5V simultaneous 50Hz/60Hz (87dB Minimum) rejection micropower 24-bit differential analog to n Differential Input and Differential Reference with digital converter with an integrated oscillator, 2ppm INL GND to V Common Mode Range and 0.16ppm RMS noise. It uses delta-sigma technology CC n 2ppm INL and No Missing Codes at 24 Bits and provides single cycle settling time for multiplexed n 0.1ppm Offset and 2.5ppm Full-Scale Error applications. Through a single pin, the LTC2413 can be n 0.16ppm Noise configured for better than 87dB input differential mode n No Latency: Digital Filter Settles in a Single Cycle rejection over the range of 49Hz to 61.2Hz (50Hz and n Internal OscillatorNo External Components 60Hz 2% simultaneously), or it can be driven by an Required external oscillator for a user defined rejection frequency. n 24-Bit ADC in Narrow SSOP-16 Package The internal oscillator requires no external frequency (SO-8 Footprint) setting components. n Single Supply 2.7V to 5.5V Operation The converter accepts any external differential reference n Low Supply Current (200A) and Auto Shutdown voltage from 0.1V to V for flexible ratiometric and re- CC n Pin Compatible with LTC2410 mote sensing measurement configurations. The full-scale differential input range is from 0.5V to 0.5V . The REF REF a T reference common mode voltage, V , and the input REFCM n Direct Sensor Digitizer common mode voltage, V , may be independently set INCM n Weight Scales anywhere within the GND to V range of the LTC2413. The CC n Direct Temperature Measurement DC common mode input rejection is better than 140dB. n Gas Analyzers The LTC2413 communicates through a flexible 3-wire n Strain-Gauge Transducers digital interface which is compatible with SPI and n Instrumentation MICROWIRE protocols. n Data Acquisition L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and No n Industrial Process Control Latency is a trademark of Linear Technology Corporation.
