TI's 12-bit, 500- To 900-MSPS ADCs Slash Board Space By 80 Percent While Providing Highest Performance

SEATTLE, June 5, 2013 /PRNewswire/ -- Today at the International Microwave Symposium (IMS), Texas Instruments Incorporated (TI) (NASDAQ: TXN) introduced a family of 12-bit, 500- to 900-MSPS analog-to-digital converters (ADCs) that reduce board space by 80 percent while providing industry-leading signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR). The ADS5409 family provides best-in-class performance in a significantly smaller footprint and at the lowest power consumption to meet the size, power and performance needs of test and measurement equipment, wideband LTE and LTE-advanced communications base stations, millimeter wave backhaul (v-band and e-band), cable infrastructure return path and defense electronics. For more information, visit


Wideband LTE and LTE-advanced power amplifier linearization previously required large, expensive and high-power-consumption feedback ADCs for speeds greater than 500 MSPS. The ADS5409 family addresses these challenges by reducing IC size, cost and power, while providing the high performance needed to achieve transmit spectral mask requirements and improved power amplifier efficiency.

The pin-compatible ADS5409 family includes six 1- and 2-channel ADCs at a variety of speed grades and price points to meet system needs.

Key features and benefits of the ADS5409 family
  • Slashes board space: 12-mm by 12-mm footprint reduces board space by 80 percent over current devices, enabling the use of wideband ADCs in applications where they would not have fit previously, such as small form factor remote radio units.
  • Increases performance-to-power ratio: Provides 2-dB higher SNR and 10-dBc higher SFDR than existing solutions at speeds up to 900 MSPS while reducing power up to 20 percent.
  • Simplifies system design: Optional 2x decimation filter eases analog filter requirements and reduces the data interface rate by half.
  • Enables linear and efficient wideband transmit: Provides power amplifier linearization bandwidths up to 900 MHz for fifth order digital pre-distortion of a 180-MHz transmit signal.
