ADS58B18IRGZT

The ADS58B18IRGZT is an 11-bit, 200-MSPS analog-to-digital converter (ADC) from Texas Instruments. It uses a pipelined architecture and includes an integrated high-impedance analog input buffer, enabling direct connection to signal sources without an external driver. The device offers a maximum sampling rate of 200 MSPS and an analog input bandwidth of 550 MHz, suitable for high-speed signal processing applications.

Key electrical specifications include a typical SNR of 66.3 dB, ENOB of 10.6 bits, and SFDR of 87.5 dBc. The input voltage range is 2 Vpp differential. Power consumption is 310 mW typical, with analog power of 258 mW and I/O power of 69 mW at 200 MSPS. The device operates from a 1.7V to 1.9V supply and over a temperature range of -40°C to 85°C.

The ADC supports both parallel CMOS and parallel LVDS data interfaces. The LVDS interface supports double data rate (DDR) with programmable swing and strength. The device also features TI-proprietary SNRBoost technology to enhance SNR over a limited bandwidth.

The ADS58B18IRGZT is housed in a 48-VFQFN exposed pad package (48-VQFN 7x7 mm) for surface mount assembly. It is RoHS compliant (unverified) and has an MSL of 1 (unlimited). This ADC is suitable for applications such as communications receivers, test and measurement equipment, and radar systems that require high dynamic performance at low power.
