The LTC2378-20 is a low noise, low power, high speed 20-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2378-20 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2378-20 consumes only 21mW and achieves ±2ppm INL maximum, no missing codes at 20 bits with 104dB SNR.
The LTC2378-20 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 1Msps throughput with no cycle latency makes the LTC2378-20 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2378-20 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
The LTC2378-20 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier’s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 • VREF and full-scale code from VREF to 0.9 • VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.

EVAL-ADMX1001
Ultra-low Distortion Signal Generator Measurement Module with Fully Differential Input Acquisition Channel
Product Detail
The ADMX1001 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator with an acquisition channel. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. The signal generator and the acquisition channel can be individually controlled using separate, easy to use, SPI interfaces - combined with the module's small-form factor, the ADMX1001 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.
APPLICATIONS
- High-end audio test
- Analog-to-digital converter characterization and test
- Sensor and transducer test
- Frequency response and network analysis
- ATE

LTC2378-20 Demo Board | 20-Bit, 1Msps, SAR ADC with 104dB SNR. Requires DC2026
Product Detail
The LTC2378-20, LTC2377-20 and LTC2376-20 are 20‑bit, low power, low noise SAR ADCs with serial outputs that operate from a single 2.5V supply. The demo manual refers to the LTC2378-20 but applies to all parts in the family, the only difference being the maximum sample rate. The LTC2378-20 supports a ±5V fully differential input range with a 104dB SNR, consumes only 21mW and achieves ±2ppm INL max with no missing codes at 20 bits. The DC1925A demonstrates the DC and AC performance of the LTC2378-20 in conjunction with the DC590 QuikEval™ and DC890 PScope™ data collection boards. Use the DC590 to demonstrate DC performance such as peak-to-peak noise and DC linearity.
