The ADCs consist of the TLA2021, TLA2022, and TLA2024 devices. The TLA2021 and TLA2022 devices are single-channel ADCs, while the TLA2024 features two differential or four single-ended inputs through a flexible input multiplexer (MUX), which provides an industry-high channel density of 0.75mm2 per channel.
All TLA202x ADCs integrate a voltage reference and oscillator; additionally, the TLA2022 and TLA2024 include a programmable gain amplifier (PGA) with selectable input ranges from ±256mV to ±6.144V, enabling both large- and small-signal measurements.
The TLA202x ADCs feature programmable data rates from 128 samples-per-second (SPS) to 3.3 KSPS and offers two conversion modes: single-shot or continuous. The ADCs’ I2C-compatible interface supports I2C bus speeds up to 400kbits per second (kbps) and a single address pin.
The 1.5mm × 2.0mm X2QFN devices operate from a wide supply range of 2.0V to 5.5V over a temperature range of minus 40 to 85 degrees Celsius.
