The TLV1508 and TLV1504 are a family of high performance, 10-bit low power, 3.86µs, CMOS analog-to-digital converters (ADC) which operate from a single 2.7-V to 5.5-V power supply. The converters include an 8-byte FIFO for capturing conversion results. The TLV1508 and TLV1504 provide SPI (CPOL = 0, CPHA = 0)/DSP-compatible serial interfaces with SCLK up to 20 MHz.
The TLV1504 and TLV1508 are 10‑bit, low‑power, serial analog‑to‑digital converters that operate from a single 2.7‑V to 5.5‑V supply. They provide 4‑channel (TLV1504) or 8‑channel (TLV1508) multiplexed inputs, up to 200 KSPS throughput, and a SPI‑compatible 4‑wire interface (CS, SCLK, SDI, SDO).
The devices include on‑chip reference options, programmable sampling periods, auto‑power‑down modes, and are offered in PW, DW, and other small‑outline plastic packages. Operating temperature ranges from –40 °C to 85 °C.
| Supply Voltage | 2.7 V to 5.5 V |
|---|---|
| Maximum Throughput | 200 KSPS |
| Analog Input Channels | 4 (TLV1504) / 8 (TLV1508) |
| Low Operating Current | 1.0 mA at 3.3 V |
| Source Impedance Requirement | ≤ 1 kΩ |
| Operating Temperature | -40 °C to 85 °C |
| Package Type | PW (R‑PDSO‑G**) plastic small‑outline package |
The devices draw a low operating current of 1.0 mA at a 3.3 V supply.
TLV1504 provides 4 analog input channels, while TLV1508 provides 8 channels.
The PWDN pin powers down both analog and reference circuits when held low.
The serial interface uses chip select (CS), serial clock (SCLK), serial data input (SDI) and serial data output (SDO).
