The MAX1444 is a 10-bit, 3V analog-to-digital converter (ADC) that features a pipelined 10-stage ADC architecture with fully differential wideband track-and-hold (T/H) input and digital error correction incorporating a fully differential signal path. This ADC is optimized for low- power, high dynamic performance applications in imaging and digital communications.
The MAX1444 is a 10‑bit, 3 V analog‑to‑digital converter featuring a pipelined 10‑stage architecture, fully differential track‑and‑hold input, and digital error correction. It operates from a single 2.7 V to 3.6 V supply and consumes only 57 mW in normal mode, delivering 59.5 dB SNR at a 20 MHz input frequency. The device includes an internal 2.048 V bandgap reference and offers flexible reference options for higher accuracy.
The ADC is supplied in a 5 mm × 5 mm 32‑pin TQFP package and is specified for an industrial temperature range of –40 °C to +85 °C. Electrical characteristics such as a 400 MHz –3 dB input bandwidth, 74 dBc SFDR at 20 MHz, and low‑power shutdown mode (5 µA) are provided, along with detailed timing, pin configuration, and package drawings.
