HI-1818A

HI-1818A, HI-1828A TM Data Sheet July 1999 File Number 3141.2 Low Resistance, Single 8-Channel, and Differential 4-Channel, CMOS Analog Multiplexers The Hl-1818A and HI-1828A are monolithic, high performance CMOS analog multiplexers offering built-in channel selection decoding plus an inhibit (enable) input for disabling all channels. Dielectric Isolation (Dl) processing is used for enhanced reliability and performance (see Application Note 521). Substrate leakage and parasitic capacitance are much lower, resulting in extremely low static errors and high throughput rates. Low output leakage (typically 0.1nA) and low channel ON resistance (250Ω) assure optimum performance in low level or current mode applications. The HI-1818A is a single-ended, 8-Channel multiplexer, while the HI-1828A is a differential 4-Channel version. Either device is ideally suited for medical instrumentation, telemetry systems, and microprocessor based data acquisition systems. For MIL-STD-883 compliant parts, request the HI-1818A/883.
