Maxim MAX1449 10-Bit 105Msps Single 3.3V Low-Power ADC with Internal Reference Datasheet
The MAX1449 is a 10‑bit analog‑to‑digital converter optimized for low‑power, high‑dynamic‑performance applications such as ultrasound imaging, CCD imaging, and digital set‑top boxes. It uses a pipelined 10‑stage architecture with a fully differential input stage, a wide‑band track‑and‑hold, and digital error correction. The device operates from a single 2.7 V to 3.6 V supply and includes a 2.048 V precision bandgap reference.
Typical specifications include a 105 Msps sampling rate, 58.5 dB SNR at 20 MHz, 72 dB SFDR at 20 MHz, and a -3 dB input bandwidth of 400 MHz. The MAX1449 is offered in a 32‑pin TQFP package (5 mm × 5 mm) and is rated for an industrial temperature range of –40 °C to +85 °C. Power consumption is 62 mA in normal operation and 5 µA in shutdown mode.
