It accepts either differential or single-ended inputs across four or eight channels, selected through the SPI-compatible serial interface. The analog and digital supplies share a common 2.7V to 5.25V range, which simplifies rail design — one clean 3.3V or 5V supply runs the whole device. Sampling at 133k samples per second, it targets medium-speed data-acquisition tasks: industrial sensor multiplexing, battery-monitoring front ends, and portable instrumentation where 10-bit resolution is sufficient and the SPI bus keeps the pin count low. ## 133k SPS — what that sampling rate buys you At 133k samples per second, each conversion completes in roughly 7.5 µs. That is fast enough to oversample a 10 kHz signal by more than 10×, or to round-robin through eight channels at over 16 kHz each. The SAR architecture gives deterministic conversion time — no pipeline delay to budget — so the SPI readback timing is predictable down to the clock edge. If your system scans thermocouples, strain gauges, or 4-20 mA loop signals at moderate update rates, this part keeps the bus transactions short and the processor overhead low. ## Input configuration: differential or single-ended, four or eight channels The input multiplexer can be wired for four differential pairs or eight single-ended inputs, selected through the serial interface. Differential mode rejects common-mode noise on long sensor leads — useful when the ADC sits on a different board from the signal source. Single-ended mode gives you more channels per package for monitoring DC levels like supply voltages or potentiometer wipers. The reference is external, so you set the full-scale range with a precision voltage reference that matches your sensor's output span. ## Package and environment: 20-SSOP, 0°C to 70°C Housed in a 20-pin SSOP (5.3 mm body width), the MAX148BCAP+ is a surface-mount part suited for automated assembly. The operating temperature range is 0°C to 70°C — commercial grade, intended for indoor equipment, benchtop instruments, and controlled environments. If your design lives in an unconditioned enclosure or sees freeze-thaw cycles, you would step up to the industrial-temperature variant of this family. ## Lifecycle and sourcing reality Maxim lists the MAX148BCAP+ as Active with ROHS3 compliance. For BOM planning that means no urgency to qualify a drop-in replacement today — but it is always wise to monitor the manufacturer's PCN feed.","metaTitle":"MAX148BCAP+ 10-bit SAR ADC, 133k SPS, SPI, 20-SSOP","metaDescription":"MAX148BCAP+ 10-bit SAR ADC with 133k sampling rate, SPI interface, differential/single-ended inputs, 2.7V-5.25V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"10","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","Reference Type":"External","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"4, 8","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"20-SSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.7V ~ 5.25V","Voltage - Supply, Digital":"2.7V ~ 5.25V","Sampling Rate (Per Second)":"133k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.73","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.73000","currency":"USD"},{"qty":10,"price":"$9.86300","currency":"USD"},{"qty":25,"price":"$9.45480","currency":"USD"},{"qty":100,"price":"$8.33030","currency":"USD"},{"qty":250,"price":"$7.92144","currency":"USD"},{"qty":500,"price":"$7.41036","currency":"USD"},{"qty":1000,"price":"$6.79710","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/54721123c12ae37a0eaabdaba6947a40.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MAX148BCAP+ and get a price?","answer":"The MAX148BCAP+ is sourced through independent distribution and quoted to order against an RFQ.
