TLV1504IDR - 10-Bit 200kSPS 4-Ch SAR ADC, SOIC-16 | TI
MPN: TLV1504IDR ✓ فعالTLV1504IDR جائزہ
An SAR ADC is a successive-approximation-register analog-to-digital converter that uses a comparator, a DAC, and a binary-search register to digitize an analog input in N conversion cycles for N-bit resolution. SAR ADCs are valued for deterministic latency, no-pipeline delay, and excellent DC accuracy, fitting between low-resolution delta-sigma ADCs and high-speed pipeline ADCs in the data-converter family hierarchy: ADC -> data converter -> mixed-signal IC -> power management & signal chain IC -> semiconductor.
Key features include four analog input channels with a programmable auto-channel sweep sequencer, a high-speed 3-wire serial interface compatible with TMS320 DSPs and SPI/QSPI/MICROWIRE hosts, programmable 8/12/16-clock or continuous conversion modes, hardware or software shutdown control, and an integrated +2.5 V reference option (TLV1504 variant) or external-reference option. Maximum conversion time is 3.86 µs and INL/DNL are specified for 10-bit accuracy across the full operating range.
Typical applications include industrial process control loop monitoring, multi-sensor data acquisition modules, portable instrumentation and battery management monitors, motor control feedback sampling, and 4-20 mA loop digitization. The wide 2.7 V to 5.5 V supply range and on-chip auto-powerdown modes allow the device to remain in the system across sleep-active cycles without external power switching hardware.
When designing with this device, ensure the SPI master supplies 8, 12, or 16 SCLKs per conversion per the datasheet; underrun or overrun of SCLKs corrupts the conversion register. The auto-channel sweep feature requires the sequencer to be initialized after each power-up, otherwise channel order is undefined.

Industrial Process Control Loop Monitoring
The TLV1504IDR suits 4-20 mA loop monitoring with its 4 single-ended inputs and 200 kSPS sample rate. The SAR architecture provides deterministic latency critical for closed-loop PID control at update rates up to 50 kHz per channel. With 1.6 mA supply current and 2.7-5.5 V operation, it integrates directly into PLC analog input modules powered by 24 V industrial rails stepped down to 5 V. The auto-powerdown mode drops current below 10 uA between scans, and the auto-channel sweep sequencer eliminates host-side multiplexer switching code.

Portable Battery-Powered Instrumentation
The TLV1504IDR's 2.7-5.5 V supply range and <10 uA powerdown current make it a strong fit for handheld DMMs, multimeters, and field-portable data loggers. Drawing 1.6 mA at full speed but dropping to 10 uA between conversions, it directly digitizes 4 sensor inputs from a single Li-ion or 3xAA battery stack. The hardware SHDN pin enables a power button to wake the ADC for each measurement, while the 10-bit resolution is sufficient for temperature, voltage, and pressure transducer readouts typical of portable instruments.

Multi-Sensor Data Acquisition Modules
The TLV1504IDR's 4 input channels with auto-channel sweep are purpose-built for sensor hub DAQs reading temperature, humidity, pressure, and gas sensors simultaneously. The SAR architecture avoids the aliasing and pipeline-delay issues of pipeline ADCs at 200 kSPS, while 10-bit resolution covers the typical 0.5-4.5 V sensor output range with adequate noise margin. The integrated auto-powerdown between sweeps reduces average current to microamps for slow-update sensors like temperature and humidity probes.

Motor Control Feedback Sampling
In brushless DC (BLDC) and stepper motor drives, the TLV1504IDR samples phase current and back-EMF voltages at 200 kSPS with deterministic SAR latency. Four channels accommodate three-phase current sensing plus a DC-bus voltage measurement in a single SOIC-16 footprint. The 10-bit resolution is adequate for FOC algorithm current loops where bandwidth dominates over resolution; the SPI interface connects directly to C2000 or Tiva motor control MCUs. Hardware shutdown enables low-power standby of the ADC when the motor is at rest.

4-20 mA Industrial Loop Digitization
The TLV1504IDR digitizes 4-20 mA current loops after a sense resistor converts current to a 1-5 V input range within the ADC's 0-VDD span. With 4 channels per IC, a single SOIC-16 ADC supports up to 4 sensor channels per PLC card slot. The 2.7-5.5 V supply matches typical PLC backplane 5 V rails, and the 10-bit resolution gives 4 mA / 1024 LSB = 3.9 uA per step - finer than the loop transmitter's 0.1% accuracy. The SAR architecture's zero-latency conversion aligns with deterministic cycle times expected by IEC 61131-3 PLC scan engines.

Automotive Sensor Interface Modules
Although not AEC-Q100 qualified, the TLV1504IDR is widely used in non-safety automotive body and chassis modules such as seat position sensors, mirror position feedback, and HVAC temperature sensing. The -40C to +85C industrial temperature range covers most cabin and under-hood-adjacent environments. The 4 single-ended channels digitize potentiometer wiper voltages, thermistor divider outputs, and switch-position contact closures with 10-bit accuracy and 200 kSPS throughput. The SOIC-16 footprint and SPI interface simplify MCU integration in space-constrained modules.

Medical Patient Monitoring Peripherals
The TLV1504IDR enables peripheral sensor digitization in medical patient-monitoring accessories such as pulse-oximeter probes, temperature patches, and spirometer flow heads. Its 2.7-5.5 V supply covers Li-ion battery operation, and <10 uA powerdown current preserves battery life between measurements. The 10-bit resolution is sufficient for oxygen saturation and respiration waveform envelopes after analog front-end conditioning. The auto-channel sweep feature sequentially reads multiple sensor elements (e.g., red/IR LED photodiodes) without host-side multiplexing code.

ڈیزائن نوٹس
Decouple AVDD and DVDD separately with 1 uF and 0.1 uF ceramic capacitors placed within 5 mm of each supply pin. AVDD and DVDD may be tied together for single-suprail designs but separating them reduces digital switching noise coupled into analog inputs. Per the TI datasheet, ground noise below 50 mVpp on AGND is required for 10-bit accuracy.
Route analog inputs (AIN0-AIN3) away from digital lines (SCLK, DOUT, DIN, CS) on the PCB. Use a ground plane on layer 2 with via stitching around sensitive analog traces. The SOIC-16 package exposes pins on 1.27 mm pitch, easily routed on 4-layer boards; place the ADC within 25 mm of the analog signal source to minimize trace capacitance.
Do not exceed 16 SCLK per conversion if using the 12-clock or 16-clock mode - extra clocks shift out junk data. After power-up, the auto-channel sweep sequencer is uninitialized; issue a software reset or a sequencer write to define the channel order before starting conversions. Do not leave SHDN floating - tie it to AVDD if hardware shutdown is unused, or quiescent current will not drop to the <10 uA spec.
The DOUT line is 3-state; tie a 100 kohm pull-up to DVDD if the host SPI peripheral requires defined idle state. For long PCB traces (>50 mm) between the ADC and host MCU, add a 33 ohm series resistor at DOUT to dampen ringing. Avoid long parallel runs between SCLK and any analog input - SCLK transitions couple charge into the sample-and-hold capacitor through parasitic capacitance.
