18-/16-Bit 250ksps to 2Msps High Performance SAR ADC Family
The LTC2379-18 leads a pin-compatible family of no-latency SAR ADCs featuring unrivaled 101dB SNR at 18 bits
and 96dB SNR at 16 bits from 250ksps to 2Msps. Explicit Busy and Chain pins, along with a user-friendly SPI interface,
simplify digital timing. A unique digital gain compression feature eliminates the need for a negative ADC driver supply while
preserving the full resolution of the ADC, dramatically lowering the total power consumption of the signal chain.
LTC2379-18: 18-Bit 1.6Msps SAR ADC Features:
•
1.6Msps Throughput Rate
•
101.2dB SNR (Typ) at fIN= 2kHz
•

High SNR/SFDR Performance 16-Bit ADCs
The LTC2209 high performance family of 16-bit ADCs is designed for the most demanding wideband, low noise, signal
acquisition applications. This ADC family addresses the key requirements for maximizing performance of high sensitivity
receivers and data acquisition systems. Exceptional SFDR performance of 100dBc, combined with SNR of up to 81.6dB,
enable the ADCs to resolve low level signals in the presence of large interferers and blockers.
The LTC2209 family uses innovative ADC technology for digital receivers by incorporating two unique features that simplify
receiver design and improve system performance. The first is an internal transparent dither circuit that improves the ADCs
spurious free dynamic range response well beyond 100dBc for low level input signals. The second feature is a digital output
randomizer that dramatically reduces unwanted tones caused by digital feedback. All ADCs excluding LTC2215, LTC2216
and LTC2217 feature a programmable gain amplifier (PGA) front end that eases the ADC driver output power requirements
when driving the lower input range of 1.5Vp-p for improved distortion performance. The LTC2274 series offers a high speed,
2-wire serial interface for interfacing to the SerDes port offered on most FPGAs.

PScope Data Collection and Analysis Software Tool
The PScope tool is Linear Technology’s high speed ADC evaluation software. Using this powerful software tool, engineers
can evaluate the performance of Linear Technology’s high speed ADC and signal chain receiver family. For a simple program
it performs complicated calculations in seconds. PScope software allows engineers to evaluate the signal-to-noise ratio
(SNR), spurious free dynamic range (SFDR), total harmonic distortion (THD), as well as other key parameters of high speed
ADCs quickly and easily. PScope can also perform more complicated calculations such as intermodulation distortion from
a 2-tone test, or adjacent channel power ratios (ACPR) from a spread spectrum signal with the click of a button. It also
supports multiple channel ADCs such as the LTM9011, allowing the measurement of eight ADC channels simultaneously.
