Analog Devices, Inc. 3 V/5 V, 2 MSPS, 8-Bit, 8-Channel ADC AD7829BRUZ-1

IC ADC 8BIT PIPELINED 28TSSOP

The AD7829-1 is a high speed 8-channel, microprocessor-compatible, 8-bit analog-to-digital converter with a maximum throughput of 2 MSPS. The AD7829-1 contains an on-chip reference of 2.5 V (2% tolerance); a track/hold amplifier; a 420 ns, 8-bit half-flash ADC; and a high speed parallel interface. The converter can operate from a single 3 V ° 10% and 5 V ° 10% supply.The AD7829-1 combines the convert start and power-down functions at one pin, that is, the CONVST pin. This allows a unique automatic power-down at the end of a conversion to be implemented. The logic level on the CONVST pin is sampled after the end of a conversion when an EOC (end of conversion) signal goes high, and if it is logic low at that point, the ADC is powered down. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. Using only address decoding logic, the parts are easily mapped into the microprocessor address space.The EOC pulse allows the ADCs to be used in a stand-alone manner (see the Parallel Interface section). The AD7829-1 is available in a 28-lead, wide body, small outline IC (SOIC_W) and a 28-lead thin shrink small outline package (TSSOP).Product Highlights

1. Fast Conversion Time. The AD7829-1 has a conversiontime of 420 ns. Faster conversion times maximize the DSPprocessing time in a real-time system.
2. Analog Input Span Adjustment. The V_MID pin allows the user to offset the input span. This feature can reduce therequirements of single-supply op amps and take intoaccount any system offsets.
3. FPBW (Full Power Bandwidth) of Track-and-Hold. Thetrack-and-hold amplifier has excellent high frequencyperformance. The AD7829-1 is capable of converting fullscaleinput signals up to a frequency of 10 MHz, makingthe parts ideally suited to subsampling applications.
4. Channel Selection. Channel selection is made without thenecessity of writing to the part.
