Texas Instruments TLC2558IDW
- Part Number:
- TLC2558IDW
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3013117-TLC2558IDW
- Description:
- 12-bit, 400 KSPS ADC, 8-Ch. Serial With Powerdown
- Datasheet:
- tlc2558
Description
The TLC2558 and TLC2554 are a family of high-performance, 12-bit, low-power, 1.6 μs CMOS analog-to-digital converters (ADCs) that operate from a single 5 V power supply. They feature a 4-wire SPI interface for direct connection to microprocessors and DSPs, and an optional frame sync (FS) signal for use with DSPs.
The ADCs have an on-chip analog multiplexer that can select any analog input or one of three internal self-test voltages. The sample-and-hold function can be automatically started after the fourth SCLK edge (normal sampling) or controlled by a special CSTART pin to extend the sampling period (extended sampling). The normal sampling period can also be programmed as short (12 SCLKS) or long (24 SCLKS) to accommodate faster SCLK operation.
The TLC2558 and TLC2554 are designed for low power consumption, with power-saving features including software/hardware/auto power down modes and programmable conversion speeds. They use the external SCLK as the source of the conversion clock to achieve higher conversion speeds (up to 1.6 μs with a 20 MHz SCLK).
Features
12-bit resolution
400 kSPS maximum throughput
Built-in reference and 8x FIFO
Differential/integral nonlinearity error: ±1 LSB
Signal-to-noise and distortion ratio: 69 dB, f = 12 kHz
Spurious free dynamic range: 75 dB, f₁ = 12 kHz
SPI/DSP-compatible serial interfaces with SCLK up to 20 MHz
Single supply 5 Vdc
Analog input range: 0 V to supply voltage with 500 kHz BW
Hardware controlled and programmable sampling period
Low operating current (4 mA at 5.5 V external ref, 6 mA at 5.5 V, internal ref)
Power down: software/hardware power-down mode (1 μA max, ext ref), auto power-down mode (1 μA, ext ref)
Programmable auto-channel sweep
Applications
Data acquisition
Process control
Medical instrumentation
Industrial automation
Consumer electronics
