MAX1338 Datasheet | Maxim Integrated

Description 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 4m A (typ), and shutdown 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. - 150ksps Sample Rate per Channel - All Four Input Channels Simultaneously Sampled 16ns Aperture Delay 100ps Aperture-Delay Matching - Channel-Independent Software-Selectable Input Range: ±10V, ±5V, ±2.5V, ±1.25V - ±17V Fault-Tolerant Inputs - Dynamic Performance at 10k Hz Input SNR: 77d B SINAD: 76d B SFDR: 98d Bc THD: -83d Bc - DC Performance INL: ±2 LSB DNL: ±1 LSB Offset Error: ±4 LSB Gain Error: ±0.1% FSR - 14-Bit Parallel Interface - Internal Clock and Reference Voltage - +5V Analog and Digital Supplies - +2.7V to +5.25V Digital I/O Supply - 56-Pin Thin QFN Package (8mm x 8mm x 0.8mm) Features Applications Multiple-Channel Data Recorders Vibration Analysis Motor Control: 3-Phase Voltage, Current, and Power Measurement Optical munication...
