TitleIC ADC 24BIT 1.6MSPS 24DFN
Description

LTC2512 from Linear Technology is a 24-bit analog-to-digital converter (ADC) with configurable digital filter. Operating from a single 2.5 V supply, this ADC features a fully differential input range up to ±VREF, with VREF ranging from 2.5 V to 5.1 V. The LTC2512 supports a wide common mode range from 0 V to VREF simplifying analog signal conditioning requirements. The ADC simultaneously provides two output codes: a 24-bit digitally filtered high precision low noise code and a 22-bit no latency composite code. The configurable digital filter reduces measurement noise by low-pass filtering and down-sampling the stream of data from the SAR ADC core, giving the 24-bit filtered output code. This ADC comes in a small 24-pin DFN package and two temperature ranges of 0°C to +70°C and -40°C to +85°C. The LTC2512 is ideal for seismology, energy exploration, and automatic test equipment.

DESCRIPTION

The is a low noise, low power, high-performance 24-bit ADC with an integrated configurable digital filter. Operating from a single 2.5V supply, the LTC2512-24 features a fully differential input range up to VREF, with VREF ranging from to 5.1V. The LTC2512-24 supports a wide common mode range from 0V to VREF simplifying analog signal conditioning requirements. The LTC2512-24 simultaneously provides two output codes: a 24-bit digitally filtered high precision low noise code, and 22-bit no latency composite code. The configurable digital filter reduces measurement noise by lowpass filtering and down-sampling the stream of data from the SAR ADC core, giving the 24-bit filtered output code. The 22-bit composite code consists a 14-bit code representing the differential voltage and an 8-bit code representing the common mode voltage. The 22-bit composite code is available each conversion cycle, with no cycle of latency. The digital filter can be easily configured for 4 different down-sampling factors by pin strapping. The configurations provide a dynamic range at 400ksps and at 50ksps. The digital lowpass filter relaxes the requirements for analog anti-aliasing. Multiple LTC2512-24 devices can be easily synchronized using the SYNC pin.
