1 / 68 page  ADS911x 18-Bit, 20MSPS SAR ADC With Fully Differential ADC Input Driver 1 Features • High-speed and low-power: – ADS9119: 20MSPS, 274mW – ADS9118: 10MSPS, 83mW – ADS9117: 5MSPS, 59mW • Feature integration: – Integrated ADC driver – Integrated precision reference – Common-mode voltage output buffer • High performance: – 18-bit no missing codes – INL: ±0.8LSB, DNL: ±0.4LSB – SNR: 95.5dB • Wide input bandwidth: – ADS9119 and ADS9118: 90MHz (–3dB) – ADS9117: 45MHz (–3dB) • Serial LVDS interface: – SDR and DDR output modes – Synchronous clock and data output • Extended operating range: –40°C to +125°C 2 Applications • Power analyzers • Source measurement units (SMU) • Marine equipment • Servo drive position feedback • DC power supplies, AC sources, electronic loads 3 Description The ADS911x is a family of 18-bit, high-speed, analog-to-digital converters (ADCs) with an integrated driver for the ADC inputs. The integrated ADC driver simplifies the signal chain, reduces power consumption for precision applications, and supports high-frequency signals beyond 1MHz. By not requiring an external decoupling capacitor, the integrated ADC reference buffer is optimized for wide bandwidth applications. The ADS911x uses a serial LVDS (SLVDS) data interface that enables high-speed digital communication while minimizing digital switching noise. Read the dual-channel ADC data using separate SLVDS outputs per ADC channel or one SLVDS output for both ADC channels.
