Product details
Overview
ADC0804S040TS/C1:1 from NXP Semiconductors is an 8-bit, 40 MHz sampling-rate analog-to-digital converter optimized for professional video digitization and high-speed transient signal capture. It delivers 7.8 effective bits at 4.43 MHz full-scale input, supports TTL/CMOS-compatible digital I/O, and operates with separate 5 V analog/digital supplies and a 3.3 V output supply. Its single-cycle conversion and no missing codes guarantee simplify timing-critical acquisition in radar and GPS receiver front-ends.
For engineers reviewing the ADC0804S040TS/C1:1 datasheet, ADC0804S040TS/C1:1 pinout, ADC0804S040TS/C1:1 application, or ADC0804S040TS/C1:1 equivalent, key selection factors include its 40 MHz maximum clock frequency, external reference ladder architecture, In-Range (IR) CMOS output signaling, low 175 mW typical power dissipation, and SSOP28 package compatibility with high-density video processing PCB layouts.
Technical Context
The ADC0804S040TS/C1:1 employs a flash-based architecture with resistor ladder reference network (pins RB, RM, RT) requiring external voltage sourcing. Conversion is triggered on each rising clock edge, completing in one clock cycle without internal sample-and-hold or buffer amplifiers.
Its digital interface features three independent supply domains-VCCA/VCCD for analog/digital logic and VCCO for outputs-enabling level-shifting between 3 V and 5.25 V. The IR output flag and two's complement/binary mode selection via TC and OE pins support flexible data alignment in real-time signal chains.

FAQ
What is the maximum clock frequency supported by ADC0804S040TS/C1:1?
The ADC0804S040TS/C1:1 supports a maximum clock frequency of 40 MHz, as confirmed in Table 6 and Quick Reference Data of the official NXP datasheet. This enables real-time sampling of analog signals up to 15 MHz bandwidth while maintaining 7.8 effective bits of resolution at 4.43 MHz input. Exceeding 40 MHz may result in timing violations and degraded linearity performance for ADC0804S040TS/C1:1.
Does ADC0804S040TS/C1:1 include an internal voltage reference?
No, ADC0804S040TS/C1:1 requires an external source to drive its reference ladder via pins RB, RM, and RT. The datasheet explicitly states that applications needing internal reference regulation should use the ADC1003S040 family instead. For ADC0804S040TS/C1:1, users must supply precise voltages (e.g., 1.3 V on RB and 3.67 V on RT) to establish the 2.37 V differential reference span.
What are the supply voltage requirements for ADC0804S040TS/C1:1?
ADC0804S040TS/C1:1 requires three independent supplies: VCCA and VCCD at 4.75–5.25 V for analog and digital logic, and VCCO at 3.0–5.25 V for output drivers. The datasheet specifies tight supply difference limits (e.g., |VCCA − VCCD| ≤ 0.2 V) and mandates separate decoupling capacitors per supply pin to ensure stable operation of ADC0804S040TS/C1:1.
How does the In-Range (IR) output function on ADC0804S040TS/C1:1?
The IR pin on ADC0804S040TS/C1:1 is an active HIGH flag indicating that the analog input VI falls within the valid conversion range defined by VRB and VRT. When VI < 1.475 V or > 3.495 V, IR goes LOW to signal underflow or overflow. This hardware-level status eliminates software polling overhead and enables immediate exception handling in real-time systems using ADC0804S040TS/C1:1.
Is ADC0804S040TS/C1:1 pin-compatible with other members of the ADC0804S family?
Yes, ADC0804S040TS/C1:1 shares identical SSOP28 pinout and package (SOT341-1) with ADC0804S030TS and ADC0804S050TS. All three variants use the same pin configuration, reference ladder interface, and timing architecture-allowing drop-in replacement based on required sampling rate without PCB redesign for ADC0804S040TS/C1:1.
