ADC Single 150ksps 14-bit Parallel 56-Pin TQFN EP, MAX1338ETN+, Maxim Integrated

Описание

The MAX1338 14-bit, analog-to-digital converter (ADC) offers four simultaneously sampled, fully differential input channels, with independent track-and-hold (T/H) circuitry for each channel. The input channels are individually software programmable for input ranges of ±10V, ±5V, ±2.5V, and ±1.25V. The input channels feature fault tolerance to ±17V. The internal T/H circuits have a 16ns aperture delay and 100ps aperture-delay matching. A 14-bit parallel bus provides the conversion result with a maximum per-channel output rate of 150ksps (600ksps for all four channels). The MAX1338 has an on-board oscillator and 2.5V internal reference. An external clock and/or reference can also be used. The MAX1338 operates from a +5V supply for analog inputs and digital core. The device operates from a +2.7V to +5.25V supply for the digital I/O lines. The MAX1338 features two power-saving modes: standby mode and shutdown mode. Standby mode allows rapid wake-up and reduces quiescent current to 4mA (typ), and shut-down mode reduces sleep current to less than 10µA (typ). The MAX1338 is available in an 8mm x 8mm x 0.8mm, 56-pin, thin QFN package. The device operates over the extended -40°C to +85°C temperature range.
