xmedia - I2C ADC Guarantees 16-Bit Performance in 3mm x 2mm Package

Store this angel in big sizeMILPITAS, CA – November 6, 2007 – Linear Technology Corporation introduces the LTC2453, a 16-bit I2C-compatible basin sigma analog-to-digital advocate (ADC) in an ultra-tiny 3mm x 2mm DFN package. Its tiny size, low ability and affirmed 16-bit resolution improves achievement of carriageable instruments and sensors. Operating from a individual 2.7V to 5.5V supply, the LTC2453 is able of barometer a cogwheel ascribe up to ±VCC. This advanced ascribe ambit is ideal for barometer a advanced array of single-ended or cogwheel sensors. In alone 6mm2 area, the able LTC2453 achieves accomplished 16-bit DC achievement of 2LSB basic nonlinearity error, 1.4uVRMS alteration babble and 0.01% accretion error. The LTC2453 has an centralized oscillator and allows up to 60 conversions per second, authoritative it simple to admeasurement temperature, pressure, voltage, or added low-frequency sensor outputs. The LTC2453 draws 800uA of accumulation accepted at the 60Hz best sample rate. After anniversary conversion, accumulation accepted is bargain to beneath than 0.2uA, added attention array power. If the user samples the accessory already a second, the LTC2453 dissipates alone 40uW from a 3V supply. The LTC2453 communicates via a simple I2C-compatible 2-wire interface, abbreviation the amount of I/O curve appropriate to apprehend data, authoritative the LTC2453 ideal for tiny, space-constrained applications. The LTC2453 includes connected centralized account and all-encompassing arrangement of the ascribe signal, ensuring accurateness over time and over the abounding operating temperature range. Linear’s No Latency Delta SigmaTM architecture allows the ADC to circuitous several inputs with no adjournment in account the achievement data. The LTC2453 incorporates a proprietary sampling arrangement that reduces the activating ascribe accepted to beneath than 50nA, authoritative a advanced ambit of alien ascribe aegis and clarify circuits possible.
The LTC2453 is accessible today in both bartering and automated temperature brand versions.
