FEATURES Small and thin 3 mm × 4 mm × 1 mm surface-mount package High SNR of 61 dBA High sensitivity of −26 dBFS Flat frequency response from 100 Hz to 15 kHz Low current consumption: <650 μA High PSRR of 80 dBFS Fourth-order Σ-Δ modulator Digital PDM output Compatible with Sn/Pb and Pb-free solder processes RoHS/WEEE compliant APPLICATIONS Smartphones and feature phones Digital video cameras Bluetooth headsets Video phones Teleconferencing systems GENERAL DESCRIPTION The ADMP421 is a low cost, low power, digital output bottom- ported omnidirectional MEMS microphone. The ADMP421 consists of a MEMS microphone element, an impedance converter amplifier, and a fourth-order Σ-Δ modulator. The digital inter- face allows for the pulse density modulated (PDM) output of two microphones to be time multiplexed on a single data line using a single clock. The ADMP421 has a high SNR and high sensitivity, making it an excellent choice for far field applications. The ADMP421 has a flat wideband frequency response resulting in natural sound with high intelligibility. Low current consumption and a sleep mode enable long battery life for portable applications. A built- in particle filter provides high reliability. The ADMP421 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard. The ADMP421 is available in a thin 3 mm × 4 mm × 1 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The ADMP421 is halide free.
