TI's ADCs Provide Highest Signal-to-Noise Ratio

8/1/2002 - Texas Instruments (TI) introduced a pair of dual 10-bit, 40MSPS analog-to-digital converters (ADCs) featuring 60dB signal-to-noise ratio (SNR) — the highest SNR of comparable data converters — for baseband communications, video processing, medical imaging and portable instrumentation. SNR represents the most important figure of merit in numerous imaging applications. The 60dB SNR of TI's low-power converters will allow ultrasound systems to scan deeper, and optical systems to realize better color gradation.

"The ADS5203 and ADS5204 successfully meet customers' speed, performance and power requirements, and when combined with our high-speed driver op amps, allow TI to offer a complete solution for baseband, video and imaging applications," said Ed Fullman, marketing manager for TI's high-speed data converter products.

The ADS5203 and ADS5204 feature +3.3V single-supply operation, low power consumption (240mW and 275mW, respectively) and 73dB spurious-free dynamic range. The ADS5204 also features a 0dB to 18dB programmable gain amplifier (PGA) with a serial control interface. The on-board PGA allows the user to adjust the gain of each set of inputs in order to match the amplitude of the incoming signal. Both devices provide customers with several design options such as single or dual parallel output bus, single-ended or differential analog inputs, internal or external reference and a power down mode.

Depending on the application requirements, the ADS5203 or ADS5204 are suitable for pairing with many of TI's high-speed op amps, such as the THS4141 (+5V), THS4502 (+5V), OPA2691 (+5V), OPA2684 (+5V), OPA2634 (+3V) or THS4121 (+3V).

The ADS5203 and ADS5204 are also designed to work with TIs high-performance TMS320C6000TM DSP platform, which is used in applications ranging from high-resolution medical imaging to third-generation wireless communications infrastructure.

Available Today
The ADS5203 and ADS5204 come in a TQFP-48 package, and are available now from TI and its authorized distributors. Suggested resale price in 1,000 piece quantities is $9.19 for the ADS5203 and $10.49 for the ADS5204.
