Linear Technology LTC2323-16 5 Msps Dual SAR ADC
Linear Technology offers a dual, 16-bit, 5 Msps simultaneous sampling, successive approximation register (SAR) ADC with flexible differential inputs
Linear Technology Corporation introduces the LTC2323-16, a dual, 16-bit, 5 Msps simultaneous sampling, successive approximation register (SAR) ADC with flexible differential inputs. The LTC2323-16 supports a wide input common-mode range and simplifies system-level design by relaxing the signal conditioning requirements to drive the ADC with a wide range of analog signals up to Nyquist frequencies.
The LTC2323-16 leads a family of 16-, 14- and 12-bit SAR ADCs, featuring sample rates of 5 Msps and 2 Msps while achieving 81 dB SNR at 16 bits, 80 dB SNR at 14 bits, and 73 dB SNR at 12 bits. The 14- and 12-bit versions feature sign-plus magnitude transfer functions, making them ideally suited for control-loop applications. The LTC2323 family integrates a precision bandgap reference with low drift and guaranteed 20 ppm/°C maximum temperature coefficient into a small 20 mm² QFN-28 package. The devices can be powered from a 3.3 V or 5 V supply and consume just 55 mW with a 3.3 V supply and 80 mW with a 5 V supply. The high-speed SPI-compatible CMOS or LVDS serial interface is ideal for highly-integrated high-speed systems.
The LTC2323-16 is available today in commercial, industrial, and automotive (-40°C to 125°C) temperature grades.
