DescriptionThe TC3403VQR belongs to TC3403 family is a low cost, low power analog-to-digital converter based on Microchip's Sigma-Delta technology and it will perform 16-bit conversions (15-bit plus sign) at up to eight per second. The TC3403's 2-wire microPort digital interface is used for starting conversions and for reading out the data. Driving the SCLK line low starts a conversion. The TC3403 is optimized for use as a microcontroller peripheral in low cost, battery operated systems. The part automatically sleeps when not performing a data conversion. The TC3403 is available in a 16-Pin PDIP and a 16-Pin QSOP package. A voltage reference is included, or an external reference can be used. A VDD monitor with a reset generator provides Power-on Reset and Brown- out protection while an extra threshold detector is suitable for use as an early warning Power Fail detector, or as a Wake-up Timer. After the conversion starts, each additional falling edge (up to six) detected on SCLK for t4 seconds reduces the A/D resolution by one bit and cuts conversion time in half. After a conversion is completed, clocking the SCLK line puts the MSB through LSB of the resulting data word onto the SDAT line, much like a shift register.
The features of TC3403VQR can be summarized as (1)16-bit resolution at eight conversions per second, adjustable down to 10-bit resolution at 512 conversions per second; (2)1.8V-5.5V operation, low power operating 280A; sleep: 93A; (3)four single-ended inputs with built-in multiplexer; (4)microport serial bus requires only two interface lines; (5)uses internal or external reference; (6)automatically enters sleep mode when not in use; (7)VDD monitor and reset generator operational in shutdown mode; (8)early warning power fail detector, also suitable as wake-up timer operational in shutdown mode.
The absolute maximum ratings of TC3403VQR are (1)supply voltage: 6.0V; (2)voltage on pins: PFO, RESET: (GND 0.3V) to 5.5V; (3)input voltage (all other pins): (GND 0.3V) to (VDD + 0.3V); (4)operating temperature range: 0°C to 85°C; (5)storage temperature: -65°C to +150°C(*Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.).
