AD1380

OBSOLETE 00764-001 FEATURES Complete sampling 16-bit ADC with reference and clock 50 kHz throughput ±1/2 LSB nonlinearity Low noise SHA: 300 μV p-p 32-lead hermetic DIP Parallel output Low power: 900 μW APPLICATIONS Medical and analytical instrumentation Signal processing Data acquisition systems Professional audio Automatic test equipment (ATE) Telecommunications GENERAL DESCRIPTION The AD1380 is a complete, low cost 16-bit analog-to-digital converter, including internal reference, clock and sample/hold amplifier. Internal thin-film-on-silicon scaling resistors allow analog input ranges of ±2.5 V, ±5 V, ±10 V, 0 V to +5 V and 0 V to +10 V. Important performance characteristics of the AD1380 include maximum linearity error of ±0.003% of FSR (AD1380KD) and maximum 16-bit conversion time of 14 μs. Transfer characteristics of the AD1380 (gain, offset and linearity) are specified for the combined ADC/sample-and-hold amplifier (SHA), so total performance is guaranteed as a system. The AD1380 provides data in parallel with corresponding clock and status outputs. All digital inputs and outputs are TTL or 5 V CMOS-compatible. The serial output function is no longer available after date code 0120.
