Solutions - Buffered 18-Bit Octal ADC with Picoamp Inputs Shrinks Solution Size

MILPITAS, CA and NORWOOD, MA – April 17, 2017 – Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC2358-18, an 18-bit, 8-channel simultaneous sampling successive approximation register (SAR) ADC featuring integrated picoamp input buffers. With board real estate at a premium, the LTC2358-18 brings substantial space and cost savings by eliminating front end signal conditioning circuitry normally required to drive unbuffered switched-capacitor ADC inputs. The combined component savings of three amplifiers, six resistors and two capacitors for each channel, a total of 88 components over 8 channels, saves BOM cost and significant board space and provides over 40% savings in power consumption. Picoamp inputs and 128dB CMRR over a 30VP-P common mode range enable the LTC2358-18 to directly connect to a wide range of sensors without compromising measurement accuracy.
