產品總覽

The LM12458CIV/NOPB is a 12-bit +sign highly integrated Data Acquisition System operating on just 5V. It combines a fully-differential self-calibrating 13-bit (12-bit + sign) Analog-to-digital Converter (ADC) and sample-and-hold (S/H) with extensive analog functions and digital functionality. Up to 32 consecutive conversions, using two's complement format can be stored in an internal 32-word (16-bit wide) FIFO data buffer. An internal 8-word RAM can store the conversion sequence for up to eight acquisitions through the LM12(H)458s eight-input multiplexer. The LM12458 can also operate with 8-bit +sign resolution and in a supervisory watchdog mode that compares an input signal against two programmable limits. Programmable acquisition times and conversion rates are possible through the use of internal clock-driven timers. The reference voltage input can be externally generated for absolute or ratiometric operation or can be derived using the internal 2.5V band-gap reference.
  • Single-ended or differential inputs
  • Instruction RAM and event sequencer
  • 8-channel multiplexer
  • Programmable acquisition times and conversion rates
