GENERAL DESCRIPTION
The AD9005B is a complete 12-bit A/D converter that includes on-board track-and-hold amplifier, voltage reference, and timing circuits. Featuring sampling rates from dc to 10 MSPS, the AD9005B uses a subranging converter architecture to achieve high speed and high resolution. Dynamic performance includes an SNR of 64 dB and harmonic distortion of 72 dBc with a 4.3 MHz analog input. This unit replaces its predecessor, the AD9005A. The AD9005B uses a higher level of integration than the earlier design to provide increased performance, better reliability and reduced cost. The AD9005B requires only +5 V and 5.2 V supplies (eliminating the +15 V and 15 V requirements of the AD9005A). The AD9005B will operate without board modification in
AD9005A sockets because +15 V and 15 V pins are not internally connected. All grades are fully tested for dynamic performance. Critical to the performance of the AD9005B is the use of advanced bipolar integrated circuits, custom designed for this device and manufactured by Analog Devices. The AD9005B is TTL-compatible with offset binary outputs. It is available in a 46-lead hermetic metal DIP in two temperature ranges: 0°C to +70°C commercial range and 55°C to +125°C military range (case temperature).

NOTES 11 Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operation under any of these conditions is not necessarily implied. Exposure to absolute rating conditions for extended periods of time may affect device reliability. 12 Maximum junction temperature should not be allowed to exceed +175 °C. Hybrid thermal model: tJUNCTION = tAMBIENT + PDISSIPATION × (CA) + TS TC) max where (TS TC ) max = 10°C 46-lead metal DIP: CA = 14°C/W in still air; CA = 6°C/W with 500 LFPM air flow. 13 Determined by 3 dB reduction in reconstructed output. 14 1nput at 1 dB below full scale. 15 Measured at 10 MHz encode rate. 16 Measured from ENCODE in to data out for LSB only. 17 For full-scale step input; 12-bit accuracy is attained in the specified time. 18 Recovers to 12-bit accuracy in specified time following 200% full-scale input voltage. 19 Excludes pipeline delay of two clock cycles (see timing diagram). 10 Worst case spurious in-band signal relative to input level. 11 RMS signal to RMS noise, including harmonics. 12 Worst case spurious in-band signal relative to level of input tones, which are both 7 dB below full scale. 13 Sensitivity of full-scale gain error with respect to power supply variation within supply Min/Max limits. 14 ENCODE signal rise and fall times should be less than 5 ns for normal operation. Transition from "0" to "1" initiates conversion. 15 PSRR is tested over given voltage range. Specifications subject to change without notice.
