LTC2424 - 4-/8-Channel 20-Bit μPower No Latency Delta-Sigma? ADC
LTC2424 - 4-/8-Channel 20-Bit μPower No Latency Delta-Sigma? ADC - Linear Technology（凌力尔特）
The LTC2424/LTC2428 are 4-/8-channel 2.7V to 5.5V micropower 20-bit A/D converters with an integrated oscillator, 8ppm INL and 1.2ppm RMS noise. They use delta-sigma technology and provide single cycle digital filter settling time (no latency delay) for multiplexed applications. The first conversion after the channel is changed is always valid. Through a single pin the LTC2424/LTC2428 can be configured for better than 110dB rejection at 50Hz or 60Hz ±2%, or can be driven by an external oscillator for a user defined rejection frequency in the range 1Hz to 800Hz. The internal oscillator requires no external frequency setting components.
The converters accept any external reference voltage from 0.1V to VCC. With their extended input conversion range of -12.5% VREF to 112.5% VREF (VREF = FSSET - ZSSET) the LTC2424/LTC2428 smoothly resolve the offset and overrange problems of preceding sensors or signal conditioning circuits.
The LTC2424/LTC2428 communicate through a flexible 4-wire digital interface which is compatible with SPI and MICROPOWER? protocols.
