TLV1508IPWG4 Equivalent & Substitute Parts

Part Overview

The TLV1508IPWG4 is a 10-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring 4-channel single-ended input with SAR (Successive Approximation Register) architecture. The device operates across a supply voltage range of 2.7V to 5.5V for both analog and digital domains, with a sampling rate of 200 kSPS and SPI data interface.

The TLV1508IPWG4 is classified as Obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Identifying compatible alternatives ensures design continuity and supply chain reliability.

• Input Type: Single Ended
• Sampling Rate: 200 kSPS
• Architecture: SAR
• Data Interface: SPI
• Configuration: MUX-S/H-ADC
• Number of A/D Converters: 1
• Ratio - S/H:ADC: 1:1
• Reference Type: External, Internal
• Analog Supply Voltage: 2.7V ~ 5.5V
• Digital Supply Voltage: 2.7V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 20-TSSOP
• Mounting Type: Surface Mount

The TLV1508IPW is identified as a parametric equivalent substitute. Both parts share identical electrical specifications and package configuration, with differences limited to product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TLV1508IPW serves as a direct parametric equivalent to the TLV1508IPWG4. Both devices maintain identical electrical performance specifications and physical package dimensions, ensuring functional interchangeability in circuit designs.

The primary distinction between these parts is product lifecycle status. The TLV1508IPWG4 is classified as Obsolete, while the TLV1508IPW carries Last Time Buy status, indicating limited future availability. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements.

Selection between these parts should be based on supply chain availability and procurement timelines. The TLV1508IPW represents the recommended choice for new designs and ongoing production due to its Last Time Buy status, which provides a defined procurement window before complete discontinuation.
