Texas Instruments - Smultaneous sampling ADCs for power quality management, power protection and motor control applications
Texas Instruments has introduced a family of 16-, 14- and 12-bit simultaneous sampling successive approximation register (SAR) analog-to-digital converters (ADCs) with high-voltage inputs. The ADS8556, ADS8557 and ADS8558 offer a sampling range of 730 kSPS and signal-to-noise ratio (SNR) up to 91.5 dB, and include the industry’s only simultaneous sampling ADC that offers true, 16-bit no missing codes (NMC) performance.
The new ADCs allow designers to maximize performance when connecting to a wide range of inputs or sensor types in applications including multi-axis motor control, simultaneous data acquisition, robotics, power quality management and power protection.
The device’s performance is maximized when used with TI’s low-noise operational amplifiers: the low-noise, high-precision OPA827 featuring a FET input for high-impedance output sources; and the OPA211, TI’s low-power, lowest noise ±18-V op amp. These ADCs work well with many microcontrollers and embedded controllers, including TI's TMS320F2812.
